Re: 69 k20 rockwell to np205 swap

I have done this swap several time I used the complete tranny transfer case and crossmember for the swap
Which transmission did you have sm420 or sm465 ?

The 465 np205 with matching crossmemeber
It will sit back further and need new holes
420 t221 vs 465 205 combo use different drive shaft length as well I can not say about the 465 t221 combo as I have not played with that setup
