So after a ton of back and forth IMing with [MENTION=73515]ajonesnv[/MENTION] and [MENTION=2243]truckhigh[/MENTION], THANKS guys, I think I found an acceptable solution to the short and larger ID sleeves that come on the 4th Gen arms. Though [MENTION=124121]dkyleb[/MENTION] was able to get new sleeves from the eBay seller which is great, I was not able to get a response from them, but I bought mine over 6 months ago so I am OK with that. The bushings that come with these arms are good so there is no reason to replace the bushings if they are still in good condition, however I have sanded mine down so I wanted to start fresh with new proper fitting sleeves and bushings when I install my lift spindles. I contacted several manufacturers and found that Dirt King Fabrications has the best all-around Upper Arm Bushing Rebuild Kit around. Keep in mind these are eBay arms so budget is a must for me, but I don't really want to sacrifice on quality. The Dirt King Kit comes with 8 - 60684 polyurethane bushings and 4 - OD 25.4mm X ID 14mm (same as the long bolts not the 16mm ones from eBay which have caused me some shifting) X 56.007mm long plus lube for $56 plus tax and shipping. So all said and done $67.28, and if you don’t need to replace your bushings now you will have a set ready to be installed when you do. We will see how all this works out once I receive and install these along with my spindles. Again, thanks to everybody for all the very useful information!
