US delivered cars came with a 3.88 R&P in the single-side-cover trans. Many of these 3.88s have been replaced with 4.12s over the years, so the presence of the one cover doesn't guarantee a 3.88. To test without disassembly, get it in second gear and count input shaft revolutions for one revoultion of the flange. 8 turns is 3.88, and 8.5 turns is 4.12

I've also heard that these were cast from the same stronger magnesium as the fuel injection cases, anyone know about this? Craig Merrow
