Gasket material, and wheels better built windows

This is from an early to mid 1990s contractor grade window, I need replacement wheels with bracket and weatherstripping which is approximately 1/4" wide. I would like price and availability..... piece and yard.....I would like to see how much I can improve these units prior to addressing the whole house replacement of these windows. My gut is telling me, I will end up upgrading the windows..but buying time is important as well..
Thank you

Exactly what hardware are you talking about? Would you like the wheels removed from the window to get a clear picture of the wheel bracket?
There are only 5 pieces of hardware, the lock and label, two brackets similar to the plastic wheel brackets on top and two wheel brackets.

Thx

I'm going to get a calipers with other stuff, shipped out from y summer home, so it will likely be a couple of weeks delay... I will feel more comfortable with that... it's on me

I've got the measurement pics the the only unusual measurement is the measurement between the two holes and that is outside to outside. Please note the original piece I was measuring had a tab broken off, which I did not realize until I looked at the others, you will see this in the last two pics. I intend to order a set, then proceed to the other windows after identifying and replacing the weather stripping...if all goes well I will replace the rest of the items after evaluation, if it I will replace the windows....Thx
