WHEN USING ME9 (non electronic) TRANS
Modify TB linkage to add            
TV lever from pre 92- Non "E" transmission car
for TV cable operation            
lever is NS from GM
use junkyard part from 1988-1991 3800 TB            
Modify, Throttle cable BRKT
to add TV cable provision, disregard when using M13 trans            
OIL FILTER MODS
Modify oil filter adapter for remote filter lines   Call Dave Buckshaw        
(not required for normally aspirated swaps) This is the toughest part of the swap
Power Steering
#6 AN 1 ft (press hose)            
Accel Fuel rail fitting, GM saginaw to #6 AN
Flare steel end of existing pressure pipe with a 37 deg flare to accept steel #6 AN tube fitting and sleeve

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!
