The 60L uses a lower .854 5th than the 60A .821 5th; does anyone now if it's possible to swap these out? I'm looking to tighten up the ratios for my coupe.

Going to use the 60 series box with 4.62 R&P till I resolve the the issue of stringer close ratio box for my coupe (read pry open my wallet).

it seems to me they won't interchange

* Overdrive gear in the 60L is the first gear on the mainshaft, and it matches up to the cluster shaft
* In the 60A it is the last gear on the mainshaft, and matches a gear bolted to the end of the countershaft

Dave this falls under Duh!!! I've read.the tech wiki numerous times and know they changed the 60 series which is why there is a dog leg and non dog leg but for some reason I got it in my head that these boxes were like the 280ZXs where you can swap the ratios.
