I am trying to compile a list of equivalent AC Delco Part #'s for the major bolt-on engine accessories for my 1995 XJS 4.0 six. This would include AC comprssor, Power Steering pump, Alternator. I am also trying to verify that I have the 4L60E GM transmission. Also, I don't have the torque specs for the wheels. Thanks for your help in getting me dialed in.

What's the exercise? Here are a few Delco part numbers:

Compressor Delco 15-21013
Alternator Delco 321-1867 (120A Nippondenso)
Alternator Delco 321-1649 (115A Bosch)
Fuel Pump Delco EP490
Power Steering Pump Delco 36-215139
Starter Delco 323-1351

Lug nut torque depends on size. I'm not sure what's used on this car:

Lug Size Ft/Lbs Torque
7/16" 55-65
1/2" 75-85
9/16" 95-115
5/8" 135-145
12mm 72-80
14mm 85-95
