there are 4 different stands including the aluminum one. First the C2AZ-6531-B, aluminum 0.98-1.02-in. Second the C3AZ-6531-A cast iron 0.98-1.02 in. third was C3AE 6531-A 1.10 wide (hi riser) and the C5AZ-6531-A 1.10 wide. height was 2.2 in on all except the 1.72 in high riser. The std height stands use 3, 2-31/32 in long bolts and one 3-19/64 in long bolt. The long bolt fits the stand with the
oil hole. The high riser stand use 4, 2-1/2 long bolts all the same. He might have wrong stand/ bolt combo. hope this helps, Glenn.
