[68K30]

I have a 700R4 and a NP205 behind my 454 in my 68 K-30I moved the crossmember and the transfer case frame mount back 5/8", redrilled afew holes and that was it. There was enough travel in the splines the make up the difference, I have a 14 bolt rear and a non-standard driveshaft in the front, but it was an easy swap. The TV cable adjustment is critical and was a little tricky on the big block,after market tv bracket and som engineering but it works, the lockup is real easy, find a 1984 or 1985 Chevy truck or suburban and get the vacuum switch that is mounted by the brak booster, the brake switch under the dash and the plug on the trans and find a schematic for the 85 truck, real simple install and it works great.

Hope this helps
Bill
