[Fot] Fw: TR6 steel synchros

Mon Jun 6 10:21:23 MDT 2022

Brad,  assuming you have stock gear sets, Rick's steel synchros will fit
all Spitfire gearboxes except those with serial numbers starting with FC or
FD.  Here's a good listing of serial numbers:

Definitely check to see what's inside though.  Have found many race
gearboxes that have been modified (GT6 gearing etc.)

Cheers, Dave
