Re: NV4500 or 700R4
The crankshaft you have has a 2 piece rear main seal. This means you need to order a flywheel for the older 350 engine, 86 and older. I would order a clutch and flywheel for an older c30 truck with a 350 engine, say around 1978. There are 2 types. I would get a diaphram style clutch, but i don't recomend the button style clutch, unless you are really going to work truck. Button clutch has a harsh engagement, tend to chatter. I would get a pilot bushing, most clutch kits come with a bearing. The bearings fail fairly quickly, because the don't hold enough grease. Do not put grease on the bushing, it works much better to soak brass bushing in atf for a couple days, if you have the time.
