    I have a 70K5 with a SM465 and NP205. I am looking to install a 700R4 and NP208. I understand the drive shafts will be the wrong length but what about a cross member mount? Can I use the stock mount or will I need to use one from another truck?

    the x-members are different...i just did the reverse swap a few months ago....why would you want to swap out the manual?...if you are lookin for an overdrive why dont ya just save up for a NP4500 tranny...but if you are just tired of shifting then never mind the last question

    I am thinking of doing this exact swap on my '72 this summer. I found a great company that can answer most of your questions (and sell you a rebuilt 700R4) called premier performance. let me know if you want the contact info.

    they are in placentia, Ca.
    their tech line is 1-714-630-3235, the order line is 1-800-959-3235

    I'm not sure if this info is still correct, I just found out that they were bought by jetchip. you can get more info at www.jetchip.com

    let me know how your conversion goes.

    p.s. where are you located?

    Thanks for the info. I am in the North East. The truck is in PA. I have a 700r4. I think I have X-fer case lined up. I need a TH350 cross member.
