I was recently scrounging the scrappy while in search of inspiration and found a multitude of toyota IRS diffs that might work on a Locost type chassis. Seems all the information I find on google has to do with toyo 4x4 diffs. I was curious about interchangability (word?) between their early diffs. Such as will a AE86 LSD fit a Supra IRS? And what kind of power they can take? Just thought I'd drop a line and see if there were any toyota resident experts. Cheers!
