E-body Door window hardware problem!

[Mr.Cuda]

Is there anyone out there who has solution to my problem?
I have bought a kit Door Window Hardware Rollers to 70-72 E-body, original pin is 3/16 in and new 5/32 in allowing too much play so much that it cannot be riveting pin so much. The seller says his parts are right for my car.
Someone who has experience of similar and where do I find the right parts?
