Donut Fitment for '66?

[blackcloud45]

Does anyone know what later model (if any) donut type spare would fit a '66 w/ front disc brakes? I'm putting a fuel tank under the bed and don't really want the spare in the bed. Was thinking of fabbing up a bracket to put it behind the seat in the cab...

If it's five bolt, the 91-96 Caprice ones will work. Any full size RWD Cadillac, too. Lots of 80s full size GM cars also, many were dual 5x5 and 5x4.75 bolt pattern.

Crap... should have specified 6 lug

Nothing?

The factory in bed carriers actually dont take up much space, and it'd be easy to modify a floor well if you wanted it even lower

Thanks guys

colorados come with a donut spare that will fit right on, the centerbore is the right size and the bolt pattern is the same.



edit: the 6 lug spare in that link above is from a mazda b2000/b2200, it also has the big centerbore.

Awesome! Thanks

Make sure that you don't put a donut in the rear if you have posi. Put the donut on the front, and swap a good front to the rear. Different rear tire heights will burn out a posi quickly.

Cool, didn't think of that. I don't think mine is posi, so I should be good.

Thanks for this thread.

I believe even an open diff (non-posi) will suffer from greatly different rear tire sizes and having to differentiate for too far a drive. It's the main reason for the warning on the spare.
