Clutch push rod length

[Bisblue]

My truck came with the wonderful washer stack below and a spring assortment. Clutch is firm and the push rod bent at one point. Truck has a newer clutch and the throw out bearing squeaks.

I ordered a new push rod and it was way too short. I read somewhere else the gmc might need a different throw out bearing. Any more info on this? Truck is a 292 with a sm465. I'm planning a 350 swap in the near future.

Also got some pedal covers from lmc, any tricks to getting then on?

Thanks in advance.
