You need to convert to 4 speed axle shafts, when converting from a 125c transmission            
***You can re-use your 2.8 liter CV's if you have a JA2 Heavy duty brake car, usually standard with 6 cyl cars            
JA2 cars have 5 on 115 mm bolt circle wheels            
ME9 transmissions are 440T4 (aka 4T60) , 4 speed automatics used in 85-93 Centurys            
M13 is the 4T60E transmission used standard in the later 3800's, Used OEM in Centurys after 94'            
The 4T60 E is longer on the passanger side requiring a slightly shorter shaft.            
If you have light duty brakes, you have light duty axles and you need to call me!
