Which Rear Frame Rails??

[gearhead1186]

My rear frame rails on my 69 camaro need to be replaced. Im planning on using DSE's deep tub kit and their quadra-link. Since Im replacing them should I step up to some more serious rails from 21st century or competition engineering? I know I need to cut up my trunk. This is fine as its being replaced anyways. Or should I get a set from yearone, weld em in and then box em up? Thanks in advance

i got a set of 21st century frame rails. My plan is to purchase a cross member for the from of the rails. I also will be running the art morrison tri 4 bar with DSE tubs. I will be placing the frame rail 42" apart.

how much hacking is required to put in aftermarket rails??

We use Competition all the time and love the way they fit, you have to cut out the tubs and if you are going to change your frame rails I would build my own set of tubs as you can go wider and make them cleaner. here is what we just did in our 69 Camaro

If you look in the 1st picture you can see where the stock frame rail was and we move the new rail over as far as we can to clear the larger tire and still fit the fuel tank. The rest kind of give you an idea of what it takes to put these in with the tubs and how it will look.

We can fit a 345 in the back with lots of room to clear and thats a wide tire on a 19-inch wheel. Hope this helps in some way

man that looks good.. but it also looks like alot of fab work and I dont know if I can do all that. I dont need to go more than 335. What did you have to do to make those rails fit. I know they dont go in the stock location and they are contoured to the body. I also want to use my rear seat.

I got my frame rails from this place. http://autoweldchassis.com/
The quality was excellent. They do require alot of work for the install, but I'm not a pro either. The back seat will need to be cut down, but I'm not sure how much yet.

I had 2''x3'' frame rails bent for me at Art Morrison's shop. I provided them with a template that I made from the bottom side of the floor pan after I removed the sheetmetal frame by drilling out the spot welds. I don't know if they kept a computer drawing of it when they were done or not. Might be worth a call. Don was the salesman that helped me, however, the last time I was there, I heard he retired. It fit perfectly. I simply welded it to the sheetmetal for a 100% connection. You can see pictures of the rails with the suspension installed to them before the assembly was welded in, on this link. www.lateral-g.net/members/mitchell
