SA-EOI trans swing 1958-1963

not sure if im allowed to sell this yet (technically it belongs to the scouts but if we cant use it we dont really want it) hence the EOI
details and photos are in the link below as i have no idea what it is.

happy to do swaps for off road parts too

I can be contacted on here or at Spike.pickstock.racing@hotmail.com
