Door Glass installation
 

Hey guys. I’ve been restoring a 86 k20 and am in the process of putting it back together after paint. The driver door is the original 86 door but I had to replace the passenger door and I used a 73-80 door. I know I’ll have to use the 86 window regulator and armrest mount but what about the other window parts such as felt and etc? Will I have to buy two different ones for each or will they interchange? Any help would be appreciated.
