solowookie well I'm thinking that pretty much settles about any question I'd have. Phat had convinced me a long time ago to go with a crossmember, but I was just kinda curious how this subframe would compare. I guess it goes back to the fact that I could make it work, but in the long run I really won't save much. just exploring the opportunity as it arose.

pro1939 Hey fellow hot rodder,I'm doing a 41 dodge,and i talked with roy from Roys Hot rod garage and with his help i put in a Nova clip.It is narrower,and i had in and out a dozen times but it worked.i bought a 79 nova for 125 bucks,and got all i needed.Good luck.

Centerline Some things to think about.

1st. The Trans Am clip is too wide for an AD truck. In order to keep the tires inside the fenders you'll have to order rims with a great deal of back spacing. $$$$

2nd. Although it may sound like a good deal, by the time you replace the ball joints, rubber parts, rebuild the brakes etc it's going to cost you almost as much as the TCI suspension.

3rd. You may save some money up front but there will be a whole lot of labor later on trying to hang all your front-end sheet metal back on a frame that wasn't made for it. Also if you choose to narrow the clip so the tires will fit you now have to add new motor mounts etc since the stock units will be too narrow.

A lot of people seem to think that doing a clip saves a lot but it's a fallacy. What you save in money gets eaten up buying special parts to make everything work together. If it doesn't then your spending hours and hours figuring how to get all your sheet metal mounted correctly and aligning properly.

Go with the crossmember. If you have to use a clip go with a Nova, at least that won't be too wide.

solowookie there is a bodyshop up here that is really good, and if I did the subframe I'd pay them to help me put it in. he will allow me to do as much work as possible, and only charge me for his actually time helping me so cost would be minimal, and I'd have good help with this being my first project.

jalopy45 I would go for the crossmember. Cutting a frame in half then welding another section to it requires some extremely accurate measuring and someone who has a real good welding machine and a real good knowledge of welding and metals. Just seen too many screwed up jobs , that the only way to fix is with a new frame. A crossmember saddles under the frame and is a lot easier to place in the proper position.

Oldbuz I don't know about anybody else but my money tree died I would go with the sub frame and put my labor into getting it to fit that way I could spend the money saved from the kit on somthing else

what would you do - subframe vs. crossmember

ok guys what would you do?

I've been planning on doing a TCI crossmember oh Phats recommendations, but I was talking to a guy today (BTW found a 400 locally finally - won't have to pay shipping on one) and he's got a trans am subframe that is the heavy duty version, and it only needs new rotors & new bushing. (here's the kicker - its $75)

so - TCI crossmember would be nice, but would you pass up an opportunity to get the front susp. for $75, and thus get your project that much further underway?
