MG MGA - Gearbox Mounts


I have been running a 3 synchro overdrive box in my MGA. It was in need of attention and decided to replace it with a close ratio non overdrive box. The non overdrive box is to the best of my knowledge an early MGB Mk1 box.
The gearbox mount for the overdrive box was a fabricated mount welded into the chassis.
The non overdive box bolts neatly into this mount but appears to sit forward into the engine bay by about an inch and a half. As a result the engine won't go back in.
I no longer have the overdrive box so I can't measure the difference.
Can some one confirm that the gearbox mounts on the overdrive and non overdrive boxes are in slightly diiferent postions.
I had assumed that they would be the same as the overdrive was an Option on the Mk1 MGB.

Brendan,

You should copy this question to the MGB Technical BBS.
It is a question for the MGB experts.

You are correct. which is why the MGB trans mount bolts in two different positions. You are going to have to convert back to the MGA mount and use the MGA tailshaft, or cut the mount off the frame and reweld it in the right place.
