do i need to change my cross member to had a 700r4? in my 86 2wd pick up?

thanks

No you just have to relocate it. There should already be a set of holes there to remount it in the correct location.

No prob. You will need a new drive shaft too, or have yours shortened.

Your 86 has holes for the 700R4. If ya need a crossmember give me a shout. I have one collecting dust in the garage. I think it's the same as the 350th. It should have a over and under route of the exhaust pipe.

if running duals, which side is over & under the crossmember? thanks

If I remember correctly, the driverside is under and passenger is over.

My 84 is done that way but in reverse. However it currently has the TH350 in it. I thought it was a hacked up exhaust job. Didn't know that they actually went one under and one through.

My solution was to ditch the factory crossmember. I had one custom made. A boardmember made it for me. I think the routing is opposite of what I stated. It's down the driverside and up over the passengerside.

Do you know if this is the same for a 78 chevy? I'm looking to go to a 700r4.

The holes probably won't be there, but everything else applies. Check www.bowtieoverdrives.com for tons of info as well as the link gchemist posted
