Pinion setting gauge 18G191

Does anyone have one of these, and if so would they be willing to post the heights of the three steps on the setting gauge, A, B and C?

Having searched the web i can only find the height of step B as 0.820", which is for an MGA apparently. I know that there are threads explaining how to set the pinion without the gauge, but i've seen this information requested on a number of related forums without success so far, and it would be useful to know.

Gavin,
The steps were to measure the nominal thickness of the carrier bearings which are actually metric. The step B was indeed for the MGA which uses 7208B bearings (which replaces the original R&M LJT40) and measure 80x40x18mm. The step A is for the 7207B which replaces the R&M 119LJ35 bearings which measure 72x35x17mm. I hope this is of some help. If I am correct step A is 17mm and step B is 18mm. C I don't know. I don't have such a gauge to check it.
I also recommend using carrier bearings with a metal cage and not the cheapy ones with a polyamide cage.
Regards
Declan
