Thanks for replying.
I have started hunting for an R-200 with adapter in hand. And I figured that if I found a diff. with the right pinion size but wrong gearing, then I would at least grab the pinion and match it up with a desired (3.54) diff. However I haven't even been able to find the right size pinion regardless of what gear ratio...
BTW, Tomahawk, what gear ratio / condition is yours in? If I can't find one nearby I will definitely be interested in buying yours.
Thanks
