Hello
The truck as I bought it was converted from 6v to 12 volts. 12 volt battery is running a 6 volt starter I had rebuilt. I suspect the issue with grinding was caused by poor engagement of the bump floor starter rods to active the starter as it still grinds. Now that I have inspected my flywheel it’s chewed up and chew up slightly my new starter gear. So I have that issue and grinding on the transmission when shifting. I picked up this used engine and transmission hoping I could kill two birds with one stone, but apparently this may not work out too good other than hopefully the transmission is good.

Do I need to change my bell housing to use the 12 volt flywheel and starter ? I don’t want to swap out bell housing it would be better to buy a new flywheel and fix /rebuild my floor bump linkage or swap to solenoid mounted on starter.
