How I installed new window rollers

I bought the same kit for my 73 Duster. - it was specific for that 1 year. Kit said it would do both sides. Each window takes 5 rollers. On has a large stand off.
The kit came w total 6 rollers and some other stuff that didn’t need replacing.
- I need the extended larger stand off roller. Pass side was peened in. Drivers side had a nut on it. The plastic Roller diameter is the same, but swivel ball in the center is bigger and stand off is larger diameter and stand 1/4” higher that the others.

where do you find a better kit?
Or how to replace the larger roller?
Check the cabinet dept at Lowes?
Modifly the given in the kit. ?

it’s a shame you can’t get good parts.
