About 40 years ago I hired a mechanic in my British car shop  who disassembled several  gearboxes, then quit, they never went back together. This may be Austin Healey or MG; I do not know. any advice to identify is appreciated. #1 is first set of photos on cardboars, #2 is second set on cement.This part is typical of the thousands of rare original British parts 1949-1994 in my amazing Florida warehouse. I have over twelve hundred parts in my eBay store, Old English Motor Company..It is divided into 20 categories, including Austin Healey, MGB  Parts. If you do not see what you need, please ASK; I will put photos on the store for you. I owned a restoration shop or acquired parts 40 years, and built up a massive inventory, which I have moved to SEBRING, where Healey History was made.. I give free restoration advice.   1954 JAGUARS  or  1954JAGPART   . SHIPPING is by UPS in the US; please give me your phone number for the package .
