I’ll trust an SM420 with worn synchros and bearing noises over a “built” NV4500 any day of the week.

Can probably tap the face of the NV4500 to except the SM420 bellhousing. Have done it for SM465 bellhousings a few times. Can keep your clutch linkage and everything the same that way just need a new hole in the floor and a shorter driveshaft

I didn't know they had nv4500s with a parking brake. I need that for my 84 C30 dump truck. What did they come in?
