Re: LH6/6L80 into a 72 K25

I had to trim the output shaft on the transmission (and the input from the advance adapters kit on the NP205) to ensure they fit. Some 6L80 and 90's have super long output shafts. I will also have to custom fabricate a shift mount on the transmission for the transfer case shifter, since it doesn't have a bolt up like the TH350 had.

I also did some fabrication to keep my original trans cross member and mounting location. You can see the pictures on my thread.

It came together well...just takes some work.
