FYI, I don't think the rebuild cost is different, but there were two manual trans used in the 93s, the M28 and M29 series, different gear ratios and HP/Torque ratings.
The M29 is a stronger trans, rated for higher HP and torque. If you'll pulling the trans and it's a M28 then this might be a nice upgrade, finding a used M29 is tuff, they are rare, not allot of 93s had the PEG II performance option. Easiest way to tell; PEG II was 3:23 gears, 245 Z speed rated tires and 150 MPH speed-O. PEG I standard Z28/T/A/Formula had 2:73, 235 tires and 120 MPH speed-O. I'd assume the cases are the same, just the shafts and gears are different?
GR - M28 -- M29 -- 94+
1 -- 3.36 -- 2.97 -- 2.66
2 -- 2.07 -- 2.07 -- 1.78
3 -- 1.35 -- 1.43 -- 1.30
4 -- 1.00 -- 1.00 -- 1.00
5 -- 0.80 -- 0.80 -- 0.74
6 -- 0.62 -- 0.62 -- 0.50
