Those I bought at Speedway, they looked more rough than the picture they showed. Today I looked at the again for the 32 and they really look rougher than before so I bought a set on eBay (https://www.ebay.com/itm/225499630259). We shall see.
Not all corvette are the 2.5 inch size, some are 2.0 inch, I always thought they were all 2.5 too, until I got a pair from a 70's vette and they were 2.0, I was sure someone swapped them out but after running the part # they were indeed corvette items.
