Jacking Pucks C5 and C7
Are they the same size? I went to put my C5 pucks in my new C7 and they were tight enough that I didn't take a chance on pushing them any further in. Mine are the metal pucks

GM says 2 1/2 inch max diameter, which is what I purchased. The ones I had for my C6 were 3 inch diameter. If they fit the slots AND don't hit the composite rocker panels your home free!
On my 2014 C7 where I installed vertically contoured side skirts I bought 2 1/2 inch diameter x 2 inch high jack pads from Katech. One frame slot was too narrow but a file on the pad tab fixed quickly. I put a mark on that pad and used it in that slot.
For my Grand Sport all slots are fine and those pads fit. Decided to buy pads from Reverse Logic since they can be temporally bolted on for trips to a dealer or tire shop. Then, sure they are used!
