I found a np435 on Craigslist today five min from my house. So I called the guy it was listed as a ford 4 speed. I went and looked at it today and got it. I traded a billet oval air cleaner for it that I got FREE from a friend that have me two of them so it didn't cost me anything it is out of a f250 divorced transfer case. I have not opens it up yet or counted the shaft splines but it should be the right one I hope of not I'm not out anything. So now what do I Need to do get an adaptor for my d20? When I install it I will put my 2 inch body lift on and my inboard shock mounts. I am having a good day so far but like I said I have not opens it up yet
