I have a 1963 f100 292 yblock and a 3 speed manual toploader on floor. I just got a rebuilt 302 Im swaping the 292 with but I want to use the original top loader . I put a new clutch in it so I want to keep the 3 speed. So my question is what diameters and where do I get a bellhouse for a top loader to 302 for cheap? thanks

 

If they did not make other variations on the 3.03, then any 302 bell housing should have the same depth spacing and register bore diameter.
We used to have them, but I see that they're not listed on the website anymore. I actually have a '66 through '68 (I believe) part number "C6T..." cast iron truck bell housing I may be getting rid of, but that's if I find another later model one first.
I let a buddy "borrow" (use) my '71 housing and he replaced it with the '66 model. The difference is in the clutch fork pivot, but that should not matter to you as long as you have the early fork and pivot to go into the bell.

You could call Randy at Driven Auto in the Phoenix area. Having an especially good selection of '66 to '79 Bronco parts, they should have lots of stuff that should work with the small Windsor engine.
Being here in CA we might be able to work something out with my '66 housing if you don't get any joy from Arizona.

If you are not aware already, you will want a 164 tooth flywheel and matching 11" clutch. You will need to know whether your 302 uses the early 28 ounce imbalance factor, or the later 50oz imbalance. But since you say it's a "302" instead of a "5.0" (same thing, but later designation) it's probably 28oz.
Sorry if you knew that already. Wanted to bring it up just in case.

Good luck.
