73 duster window rollers

Hey guys, I have a 73 duster that’s missing most of the window rollers inside the door. I’m trying to find replacements but I am striking out. Vans auto says they don’t carry them anymore along with 520 industries saying they don’t have them. They are telling me that they’re a body window roller kit for the valiant, scamp, and dart are different and won’t work on my duster. Can anyone point me in the right direction. Classic industries shows a set on their website but it says it is for the valiant, duster, and dart all for 73 but according to those other guys they wouldn’t cross over. I’m pretty good at modifying and fabricating. Wondering if I can use their abody kit to work, but they said the wheel sizes are totally different. Thanks in advance
