ElCamino had a boxed frame also. Did the GS have a boxed frame in 65?

I didn't even think of the El Camino! That makes sense. Is that it MARTINSR? Convertibles, Z16's, and El Camino?

LOL, I forgot about the ElCamino. I was talking about the Gran Sport (not "GS", that came in 67 or 68, I forget) in 65-66 and maybe 67, I am not sure. But I know that all the 401 nailhead powered 65-66 Gran Sports had a convertible frame.

Hows this for another for those with a closet Buick interest:

In 65 (maybe 66 as well, I have only owned 65's so that is where my info is mostly) GM had a rule that no "A" body could have an engine larger than 400. So, the 401 in the 65 Gran Sport is never refered to as a 401, it is a "400". If you go to a parts store and ask for some Gran Sport engine part, it will be called a "400" and you will get the exact some part as a Wildcat would have but called a 401.

How they made any money on the 65 Gran Sport is beyond me. It was a totally different car, not like a GTO which had the exact motor, just a larger bore than a Tempest. The entire drive train is exactly the same as a Tempest.

The Gran Sport had Gran Sport only wire harness, clutch parts (it had a FORGED bell crank, looks like it came off a friggin tractor) the brakes are different, different rear end with much bigger axle bearings (those are Sport wagon I believe), different oil pan and sump than other 401's, cast iron "header manifolds", forged motormount adapters, Gran Sport only Super Turbine 300 two speed tranny, ALL 65's had bucket seats and floor shift. Different battery location, different radiator (most all AC parts are Gran Sport only). It was wild, it is like a darn hot rod built in some guys garage with an engine swap.

You could also order a HD (Heavy duty) suspsension package for your GTO, that included a boxed frame.

I was thinking about the master series epoxy primer as it will seal out oxygen and prevent further rusting. Either way my concern is how to get the material into the rocker with sufficent coverage to be effective. I used eastwood rust encapsolator on my boxed frame inards. I had to really thin it out to get coverage.

I looked at the 3M cavity wax, looks pretty good! I'm assuming I would need the extension wand.

kron,
read the epoxy tech sheet, "must be clean sanded bare steel"

sandblasted and/or sanded to remove all rust then epoxy is a fantastic rust barrier

"rust encapsulator"=find a piece of rusted scrap, spray it with the product, check it for rust after setting outdoors for a month

red65,

Thats pretty much consistent with the prep required for the 3M cavity wax (cleaned bare or primed metal). I did a "real world" test on my truck's tow hitch and was not impressed with the rust encapsolator. Thats why I was leaning towards the Master Series primer/sealer.

I'm going to give the cavity wax a try. Thanks for the responses.

kron, epoxy is a virtually a "condom" for steel, stays flexible and great barrier for O2 and H2O, (doesn't do well with sunlight UV)

"but" different parts on a car do last longer with different materials

epoxy = sand blast and/or sand all the exterior of frame and floors (and the inside of the car floors) give it 2-3 coats of epoxy= lasts 20+years(?)

yah got 3 votes for wax in the rockers, 0 for epoxy...right?

use the "search" function again, this time plug in "epoxy"
