How do I set the catch pins perfect for bench? Update

I had been lifting on a set up that I custom built in my shed.
This year, the summer heat convinced me to move my home gym indoors, so I bought a power rack from Amazon.

It seems like a nice rack, but on bench press, the bar hits the catch pins at the same time it hits my chest. This includes me puffing and expanding my chest out.
I tried putting boards under the bench to raise it 1 1/2 off the floor and that gives me good clearance off the catch pins, but now my feet are too high off the floor.


I don’t have a spotter BTW.
I’ve only ever missed a rep benching once in my life and it was before I built my custom set up. No collars on the bar, so I was able to dump the weights on the floor, but I’d prefer to avoid that.


Am I over thinking this?



Update. Because I know y’all were all very concerned about my problems

I had some left over horse stall mat. I cut it to fit inside the power rack. The rack is sitting on two mats side by side and I added a piece of mat on top of that inside the power rack. Seems like a perfect height for me now.
