I just found out this morning that Delco Remy has a great website and you can search for any part by number and it was able to give me Revised part numbers, whether they're available or not and if it's obsolete it suggests replacement starters for the cummina engine. Even better there's a number you can call for technical assistance and the guy I talked with was whiz. he said rather than trying to find that old part, I can upgrade to a new starter with solenoid that only weighs 35 pounds instead of the 65 pound part that's in there now and it's covered by a 3 year warranty I called freightliner and they had 5 of those on the shelf in Springfield Missouri. part number 8200433. This replaces the old clunker starter on my 6C 8.3 cummins engine and now has a warranty. Cost about $370 for the whole unit.
