Re: 700R4 with NP205?

Hey there, just thought I may be able to make this a little easier on you. I have done this swap on my 1980 SWB k10 and loved it....until I realized the guy at High Impact Transmissions neglected to tell me a dual cardan driveshaft would not fit due to clearance issues with the trans pan. I live in MN and require this for extra traction on the highway in nasty weather. However it is possible to use a front driveshaft with only one u-joint on each end if you are only using it at lower speeds crawling around. I paid near $3000
for this entire set-up and was pretty pissed he would not work with me in finding something that suited my needs. Anyways, I have a High Impact "BAD BOY" 700r4 which I loved and is rated for 500 horse power. It has approximately 5000 miles on it and was in my truck for one year. I have the adapter from AA, a Lokar Nostalgia floor shifter (12 inch? not the long one) Dipstck tube, kick down brackets for edelbrock 600, kick down cable, it has a lock-up converter, trans cooler, tranny temp. guage, everything! the 700r4 is already fitted with a different output shaft that allows it to spline to the earlier 205, its been a while but I think its the 10-spline input, I also have the t-case with a rebuild kit installed in it and I also made it a fixed rear yoke while I was at it. I have had this in my truck and drove it to and from school in Montana and it was perfect until later when I found out the fr shaft I needed wouldn't fit. If you need any of these parts I am willing to help you out but I am not going to give them away dirt cheap as they are all like new.

Thanks to all,
