Reverse synchronization

I have a 3 speed manual. Do these transmissions have a syncro on reverse? I have read some say you need to be at complete stop. Or put it in forward gear before going in reverse.
thanks

It depends on which transmission you have. The original 3 speed transmissions in our trucks were only synchro'd on 2nd and 3rd. First and reverse were not. So yes, it's best to come to a complete stop when shifting into either gear to prevent that nasty grinding sound.

Seems like most times I have to double clutch it to go into reverse. Not always but a lot of the time it likes to have me use the clutch again.

I do not believe any trans used in any 50's Ford truck had a synchro reverse.
My 2001 Honda didn't have a synchro reverse. I consider synchro reverse to be a fairly uncommon thing.
