Bushing spacers for LT77 remote

[relative4]

I'm replacing my LT77, and when swapping the gearshift remote from the old gearbox, I found that the bushings that mount the remote to the gearbox were toast, and that three of the four spacers for them were missing.  The one spacer I have is one of the front/upper ones.  I can get bushings from Moss, and I can match the upper/front spacer at the hardware store, but can anyone tell me the length of the lower/rear spacer?  Or a domestic source would be great too.  Thanks!
