I have a 87 f25 dually. I have owned this truck for about 5yrs with absolutely no problems until my starter bolt came out and I guess it wrecked havoc on my flywheel. So I've chewed up 2 starters since. My issue is I have the original 460 in it but the previous owner replaced the transmission with a zf5 out of a 90's f350. My question is how do I know what flywheel to buy. I'm worried that a oem flywheel for my truck year wont work and I'm thinking about replacing the clutch assembly as well. Any info that can get me pointed in the right direction is very appreciated.
