Cheap Supra Diffs

I know you Merkur people (and others likely) like to drop in those supra diffs, and there's two for sale (not mine) in the midwest right now:

$100 - LSD, should be 3.91 ratio (89.5 turbo car)

$150 - LSD, 3.73 ratio

I may pick up one if I'm nearby but figured others may be looking as well. Cheers.
