Starter Bracket Blues

[flhtc01]

Ok, so my 86 CUCV does not have a starter bracket installed. The starter has been switched over to a 12V instead of the original 24V. There is a bracket bolted to the block but, not the starter. I am thinking it may have been for the 24V starter. Are the brackets different? Does anyone know the thread size for the nuts that go on the starter that holds the bracket in place? Any and all comments welcome.

IIRC the starter end of the bracket was 1/4- 20 although newer ones could be metric

the are 2 different bracket that I know of. the older 27mt( direct drive) or the 28mt(gear reduction). the older style bracket is longer than the new one. the technical library has both set of numbers. I can't tell ya which one is which.

Thanks to both. Looks like I need to research a bit more but, you have both pointed me in the right direction.

Older one is curved, gear reduction is straight. Block should be an 8x1.25 IIRC.

M8x1.25x18mm bolt.
