Custom Trans Cross-member?

Can't help but notice all the different Transmissions we're all running in our trucks. OEM 4 speeds, automatics, later model Turbo 350s, 400s. 700R4s, Tremecs. The OEM transmission cross member being a crude piece of hat section steel. that hangs down to where most dual exhaust jobs have the head pipes routed under and hanging below it. There are a lot of great tubular steel and box channeled cross members available $150.00 - $250.00 for all the typical stuff like Camaros, Novas, etc.

Has anybody seen a reasonable priced, double hump cross-member for our 67-72 trucks that allows tucked up into the frame rails, dual exhaust (2-1/2" - 3")and works with Turbo 350-400 or 700R4s mounts? Something like this.

Thanks

Re: Custom Trans Cross-member?

i had a 64 chevy pick up. it had the factory 3 speed standard column shift. The trans was supported bt the mounts on the bell housing. I converted it to 4 speed auto. I took a double hump crossmeber from a chevelle. it was actually to wide, so I cut it down, heated up the ends and squeezed the ends closed. set it in the frame, with the tranny and mount set up. drilled bolt holes, and bolted it up. worked just great. The truck wasn't lowered, so the exasut wasn't a clearance issue.

Re: Custom Trans Cross-member?

Here is a link to one I bought. http://67-72chevytrucks.com/vboard/s...77&postcount=1

Several vendors carry this style, CPP has another version but it only attaches to the bottom of the frame c-channel.

I plan on running my exhaust above this and through the trailing arm cross member, I have a CPP trailing arm cross member though.

I saw one. It was made from 3x1 eighth wall box tube, a piece of schedule 40 3 in tube split lengthwise into two semicircular pieces and welded together with a 2 in x 4 in piece of 1/4 in plate on each end for mounting to the frame of my truck. It was drilled for the mounting bolts for the trans mount and on each end for attaching to my frame. It holds up my transmission and I fabbed it up myself at a total cost of...hold on now, it's a shocker...$15.00. The local powder coater charged me 25 bucks to coat it gloss black bringing the total to $40.00 for something I could have bought from a handful of parts houses for...what? $150.00, $200.00 or maybe $250.00 I wouldn't know because when I need something like that I make it.

Why shop for this stuff when you can make what you need? If you can't weld go down to the local community college, high school extension school or your buddies house and learn. It isn't hard, but it does take time.

Re: Custom Trans Cross-member?

heres one i cut from 1 1/2"x3" 3/16 wall in the pic it was still being mocked but after it was done it turned out awesome.

I have a trans c-member for a t-400 camaro/nova and it fits great in the truck i tried it but it still wouldnt work with my headers
