MG MGB Technical - Sierra Gearbox

Has any viewer fitted a Sierra gearbox to an 1800 MGB GT? If so can you give some tips and any mods needed to accomplish this feat.

Waiting impatiently for expertise.

Hi,

I fitted a Datsun box to my B, and have co-written a comprehensive article on how it was done. The technique should be similar with a Sierra box. If you would like a copy send me an email with your email address.

Cheers

I have had the Sierra gear box in my 1973 MGB GT for 8 years now.
I used the kit sold thru Moss Motors US.

No problems. The directions were excellent and all parts needed were supplied in the kit.

A separate mod was made to recalibrate the speedometer at a truck shop by installing a little gearbox in the cable.

After my '73 was wrecked, the engine and gear box were transfered to a 1971 B GT, this past year. runs fine.

Have one that I could sell you if you wished to do the whole thing yourself ....... too heavy for fitting in the midget, and kinda like the standard B with overdrive
