I made an error. You are correct the ratio is 3.69. Ratios are available from 3.69 to the mid 2.0's.
Several years ago I spent six months looking for differentials that would just bolt into the crossfire.
There was a common denominator for differentials that just bolted or directly replaced our differential.
I saved the info of course, but I have forgotten what I did with it. I will look after the first.

When I bought the 3.69 I also purchased an 3.67 and I have advertised it for sale but no body wants to
pay. They are not cheap but considering there is no need for structural mods it is cheap.

Tell me what ratio you are looking for and I will see what I can find.
