mikef, the 220mm US/UK/Export big diffs never came with 3.26 ratio, just 3.133:1. (Technically UK and Sweden MKIV TT 6-speed diffs might have had one other ratio option in 220mm).

^^ Nope. I looked this up and I was wrong. See post #21 below.

Have to correct my post. After looking at this:

And this:

I goofed. Apologies, mikef :/ I'd read some info a while back on how Japan changed their Supra 6-speeds to 200mm diffs after the first couple of years and either information was updated or I'd got it wrong at that time. I knew about the 3.5xx 220mm ratio being a rare variant in some European countries but I completely missed there being a 3.266 220mm ring and pinion as well as a 3.266 200mm ring and pinion.

Consider me schooled. Thanks for bringing this up.
