Well i got the big block installed in my truck and everything lined up pretty good.yesterday i installed the pass. Side header, i used the 2455 hooker comps, and it went in ok but the problem is that the collector sits about half way on the trans cross member.wat do yal guys think i should do about this?

What do you mean on? on my caprice the crossmember went right behind the collector so I couldn't add exhaust. I put on a double hump crossmember from g-force.

do you have the part number for this one. I checked them out online and the prices are not bad at all i think i might go with this one.did you have to weld the ends of it?

69trk · 07-28-2010, 08:04 PM

I'm trying to find the part number for you. I can't seem to find the receipt, which i have every receipt for the last 20 years on this truck... What i did was measured inside to inside on the frame, then found that piece on transdapt website. Yes, the ends i welded them on. I bolted the crossmember to the trans, then adjusted the ends, marked them, tacked them in place, then welded them up and shot them with some primer and black paint. Make sure you have the trans set where the original crossmember held it.. I ordered it thru summit racing or jeggs , they don't show them in their catalog..

69trk · 07-28-2010, 08:44 PM
