X2!..
Yep--#3510...a common run of the mill high torque starter, that fits most all small and big blocks in the 70's and 80's...no good for a diesel!..the one pictured looks like the later metric version with the "short" solenoid..might work on a 4.3 V6 too,and some straight sixes...
I got all excited when a guy I know said "heyyou own a GM diesel,right?..
"I have a brand new GM diesel starter I'll give you,I sold the truck I had, and the new owner never came back for it"..
When I got it,it WAS a brand new starter--but it was for an OLDS 350 Diesel!

..way different nose,with 3 bolts on the side!..should have kept it though,the bendix drive would have fit my 6.2,and I had to buy a rebuilt drive for 35 bucks for my "old" starter not long after that!...probably could have swapped my 6.2 nose on it possibly too,but I didn't think of that at the time...
