How many using an A500 overdrive ?

you had to have also swapped rear ends....most M bodies Ive come across had 2.2 or 2.45 rear ends stock..... I had one with a 2.9, still too low for an OD to work

swapped in a B body 8 3/4" with a 3.55 limited slip. even with 27" tall tires I HATED the 3.55 with the 998 lockup it had stock. way too many revs on the highway at 70-75MPH. 70mph was 3100 RPM. OD dropped it down to about 2130 RPM, or equivalent to a 2.45 rear....for what it's worth, an F/M/J body rear is within 1/2" in width to an XJ cherokee axle (cherokee is a touch wider), and you can find 3.55 geared 8.25's out of one of them just about anywhere for chump change.
