Any info would be appreciated thanks.
I think you need to re-asses the drive you currenty have as the range of drives Volvo
120S-A, 120S-B, 120S-D, 120S-E, MS25S-A, MS25SR-A
130S-A, 130S-B, 130SR-A, 130SR-B
150S-A, 150S-B, 150SR-A, 150SR-B
In general the last character in the type number tells you the revision level of the drive, so the last modification they did for the S120 is E. Revision C never made it to the sales department as far as I can tell.
The ratio is printed on the type-plate on the transmission
as they could be delivered with either 1:2.19 or 1:2.43 or thereabout. It all depends on the max-rpm of the engine
that sits in front. 3200 => 1:2.19 and 3600 => 1:2.43
Most S120 drives were supplied with the 200x series and most MS25S were supplied with the 20x0 series. The new D1-xx and D2-xx series are supplied with the 130 or 150 series.
Hope that helps.
