B3 Pinion Question

[dibble34]

Hi All

Just picked up an old B3 to see how i get on with 2wd in the spring. I have the standard 81 spur and was wondering what pinions i should be looking at for either
10x1
10x2
12x1
12x2.
I read the manual, but it only gives info if i have a 87 spur and i really don't wanna change that too.

Thanks in advance

Dave

Looks like they were using a 19t with a 11x2 so i reckon a 18t for a 10x2 wasn't a bad guess :D
