3 speed OD question

I recently picked up a nice 3-speed overdrive for my truck. It is a non-synchro with an R-10 unit on the back of it.

Do all the 3 speeds have the same first gear ratio?

Re: 3 speed OD question

IIRC some of them they put in cars came in a close-ratio version? Not sure. Put it in first and see for yourself.

AFAIK/IIRC all of them were 2.94 in trucks.
