Thanks again. The truck currently has roughly 6.60s in it, so I'm going to go for 3.50s. I'll probably just get my local trans shop to mess with the speedometer for me eventually. Until then, I'll just use my phone.
Thanks for the replies. My uncle will assist with the install and he has more tools than I would probably ever need on my lifetime. One more question. How difficult is it to adjust the speedometer for the new gearing on an NP435?

My first time installing a ring and pinion set. Is this all I need parts - wise to get the job done? Thanks for any information.
Decided to sell my '68. 300ci straight 6 and I believe a NP-435 4spd. Asking $7000. New carpet and reupholstered seat. Runs and drives. Located in Raceland, LA. Email me @ [email protected] if interested.
Once again, thanks for the info. I'm leaning toward the M5 because it looks like they're cheaper. I don't plan on towing anything except possibly a 16ft aluminum hull. I've seen that there's a m5od, m5r1, and a m5r2. What's the difference and which would be better?
I've heard of the M5OD. Would it be a direct fit? Or would the zf be easier? I like the truck as-is, but I currently use it as a daily driver and would rather not be at 4500rpm at 65mph. Thanks for the info.
