Regarding the well discussed different rear axle ratios between the automatic and manual cars, has anyone ever just changed the ring/pinion setup in their rear differential instead of swapping the whole rear end?
I ask this because the rear end from my donor car is quite rusty and would require a complete overhaul (think all seals, everything brake related etc.) and even then I'm not sure I could get the trailing arms and track rods etc freed up without a fight. The donor was so rotten I just cut thru the various suspension rods and trailing arms when removing the axle from the car.
On the other hand, the rear end on my driveable 240 (1992 245 NA, AW70 currently) is in quite good condition, and wouldn't require nearly any of the above mentioned work aside from some routine maintenance and "while I'm here" replacements. Thoughts?
