67 mustang straight 6

Hey guys. Iv got a question about older mustangs.
Today I looked at a 67 mustang with a straight 6.
A friend told me that when the floor pans started rusting on a mustang the car need a restore or the frame was in danged of collapsing
The car runs / drive and sounds great. How ever. Its squeaks (Shocks Im pretty sure)
The floor pans are rusted (The guy told me this right away) I look and they did not seam bad but are rusted.

I was wondering what are the major parts holding the car together that support the car?
My biggest worry is the car collapsing on me. Altho It was late and i didn get a great look most everything else looked good.

I know some older cars had issue with the floor pans like trans ams. Once they started rusting other thing went right along with it causing harm to the cars over all well being. Reason being is because they wear welded to supporting parts.

So if the floor pans are rusted out on the mustang is this car unsafe? Ill upload photos in a bit.

I know its hard to say with out seeing it but give me some kinda idea what to look for.

Thanks!!!

Usually, the rust that you can see represents only about 10% of the rust that's actually there. Arm yourself with an ice pick and do some poking around.
Even better, begin looking in the West and Southwest U.S. for good rust-free examples. I would never begin a project that had rust in it.

There is an integral 'K' section that runs under the floor pans and is structural. Rear of the car where the leaf springs mount is also critical and the front suspension. The rocker boxes are also structural. If those parts are solid, then the car is likely a drivable project from a structure standpoint

Agreed. Thanks to everyone. The guy said the car run great - he did say once it gets past 65 is shimies a bit. I dont mind doing repair work. I do mind this thing spilting in half. The car does need some rework (Paint and a few parts) But the
guy is only asking 2k.
The inside is beautiful.

My wife is in love with it. She has always wanted one.
Is it true - if the floor pans are rusted the rest is junk? My friend said floor pans are about 40% of the support of the frame.

Thanks. Next time I look at it ill get it on ramps and get a better look.

Check very carefully. After seeing some Mustangs on the SPI site being done by Rusty Gillis, you can see how the rust can be there but hard to spot.

There's usually a very good reason someone is letting a car go cheap.

subframe

Fox body mustangs 79-later had a weaker floor structure and cracks show up on a lot of 5.0 cars. I added a subframe kit and steel tubing under the rockers and cross pieces to the round kit rails under the center of the seats. front to back. building a ladder shape to each side and tied those to the front and rear suspension structure. early mustangs have different pieces depending on the engine -body. K engines used heavier gage rockers, convertibles had additional rocker pieces and a cross plate.
after looking at those pictures of that rusted out mustang I think that is a way too much work. There is a K engine coupe at a near by wrecking yard,. later 302 and c4 , mabe 10 % of that much rust that no one around here thinks is worth the effort to rebuild. look for a better body.

The nice thing with Mustangs is that literally every part can be sourced aftermarket. The bad part is that often you need almost every one of them to do a decent restoration. They were cheaply built, and had what today would be limited life expectancy. Then there are those that will actually break, usually at the firewall from rust. Now with all of the negatives - I really like Mustangs, they have an appeal that many other cars don't. So, with that said, you and your wife like it, the price is right, you have reasonable mechanical skills and a reasonably good source of funds, this may be a fun project. If someone else will be doing the work, it WILL get expensive - then it's probably not your dream car.

For that year Mustang a complete new tub is available with all new metal. Before tackling the rust replacement i would look at getting the new tub..The tub is the main body assembly minus the doors, trunk lid and front sheet metal..basically what is left after all the rest of the car has been removed..

You need it on a lift, not ramps. Drive the car to a tire dealer or a place that installs mufflers and pay them to put the car on their lift. Take your wife with you and let her handle the ice pick. Try to explain to her that if the basic structure of the car is breached due to rot, that in an emergency move on the highway, it could fold up and kill both of you.

You know that Ford Motor Company put only the barest minimum of metal into the car when they built it (to keep costs down) and it needs all of that metal to maintain a functional automobile. If ANY of it is rusted away, the car is unsafe.

As for the front end wobble, plan on replacing wear parts and bent or broken parts before you take the car up to speed.

It's the "Buyers Remorse" that hurts the most. Maybe take it to a good Body Shop for a second opinion .

Yep, or better yet, a good restoration shop if there is one in the area.

Personally, I would take it to someone I know I can trust....Not saying all shops are crooks, but going in there with the attitude that its all rusted out, and you may get an estimate that it is totally rusted, whereas it may not be.....Get them to show you where it is rusted, dont just take their word for it.....and maybe get a 2nd opinion too.

never buy a car that "looks beautiful", but is all rusted out.
i was hesitant on buying my 63 ranchero for 500 bucks, because it was rusted out in the same places you are talkin about.
the unibody would never be the same. even if you spent the hours to fix it.
i did take this project on, and while replacing the floor, i ran into the front substructure that was rusted out as well.

i did the ice pick trick, and it went through the 14 gauge steel.

i ended up putting the ranchero on a 71 international frame.
now its golden!

IMO, for 2 grand you can find a mostly rust free mustang with a 289 in california, ship it back, and still be under your 4k mark, with a vacation included
