Hello Barney:
I'm sure you know that the standard gear ratios for the MGA gearbox are:
1st = 3.64
2nd = 2.21
3rd = 1.37
Top = 1.00
The close ratio sets as provided by the factory were:
1st = 2.44
2nd = 1.62
3rd = 1.26
Top = 1.00
No telling how many close-ratio gearsets were produced, but there was
apparently never a shortage of them when the cars were new. It seems
they were often coupled with the optional 4.55 differential set. I
occasionally see a set or a c-r box offered for sale in club
publications. Don't know of any at the moment, however.
