What suufix is my R380 gearbox Defender 110 Hardtop TD5

Hi All,
I would like to refurbish my R380 gearbox new bearings etc.
I am having trouble on what suffix my R380 gearbox is and on ebay bearing sets are available for suffix J suffix K & L etc.
The number on my R380 gearbox is 43D024122G
What suffix bearings kit do I need to purchase?
Any recommendations, links.
Regards
Perry

99% sure that's the serialnumber of your transfer box, not gear box.

Yes correct that is the serial number for the Transfer Box and not gearbox my mistake.
What suffix am I to follow for the bearings

For what? Your gearbox or transfer box?

If transfer box then it seems most are the same - Ashcroft Transmissions

And how about the gearbox bearings

Ashcrofts stock pretty much all the bits you'll need
Ashcroft Transmissions
There's a handy guide to where to find the number too. Just forward of the oil drain plug.

Brilliant. Bet you did that without looking at the parts catalogue too.
