Has anyone done or seen a 5 speed manual swap done on a 1979 f350 4x4 or something similar? The truck currently has a 4 speed man. and 4.10 gears. I would like to drop my highway rpm without changing out my diff. gears. At 70 mph It runs about 3k. Any ideas? Thanks!

Can I still use my 205 t-case? Has anyone posted an article on this swap? thanks for the advice.

I have looked into a nv4500, most people I have seen spend around $3,000 to do that swap. By the way, my engine is a 400m. My father in law has a zf, but I dont know if it is any good.

Thanks for the help.

The zf is behind a 460. Is the zf significantly longer than the 435? Will I have to modify my driveshafts?
