I've done a lot of searching but can't find the information I'm looking for. I'm planning on installing the drum parking brake split transfer case from an early '80s BJ45 (European) behind the H41 from an '84 HJ47 (Australian). I'm trying to decide between the stock transfer case gears (along with 4.11 coarse spline differentials) or the Sumo 3:1 gears from Cruiser Outfitters (along with 3.70 fine spline differentials). I'm having trouble finding the BJ45 stock transfer gear ratios to plug into my crawl ratio spreadsheet so I can compare. Does anyone know the answer or know where I can find the answer?
I'm thinking I can count the teeth on the gears and calculate the ratio myself if I have to. Any tips on how to do the math would be appreciated.
