Re: Need np435
My only advice is that you check on the required number of splines, and length of the tranny. The NP435 had several veriations. I know the one that works is from a 70's F-series 2-wheel drive truck (not sure on the exact year). Advanced Adapters sells one for a little more than $1000. This will be your best bet.
Hope this helps.
P.S. I ate stock gears with a slightly modified 302. Even a 351 will not eat gears with a NP435. This will be a hapily spent $1000, believe me.
