i finally found the exhaust and intake cams i need, but im not sure if i bought the right ones. Why is it important to get the cams from a car that has the 8th digit D insted of T?

I found a intake from a 1995 Sunfire Quad 4 and the exahust from a 1990 Buick Skylark DOHC LO Quad 4, i didnt check the vin when i pulled them? what are the odds i got the wrong cams, and why are they different.

P.S. i searched and couldnt find anything on this topic, only that i need to find vin D cams.

T is for the 2.4 motor , not a 2.3


and the cams come from the 2.3


the 90-94 exhaust cam , and the 95 intake cam are the 1's that are needed


the 94-older intake cams , do not have the HEX drive for the power steering pump
