OK I'm still realitively new back into this stuff. we have an old utily/truckbed trailer we use for firewood and the like and I spotte the shocks yesterday and decided to crawl under and look at them today, obviously coilovers, no idea what brand or if they are rebuildable like the ones on my challenger, wich are works shocks. WHat ended up catching my eye is the two tags still bolted to the diff cover. One says "use limited slip fluid only" or something like that, the other says something like 41-10 then 4.11 wich I understand to be the gear ration that was ORGINALLY stuffed in there, not neccesarily whats in there now. It seems to be a full floater if I don't miss my guess and eyeballing the CK5 axle guide it appears to be a Dana 60. I think the bed was originally a 63 but wouldn't swear to it. Any help would be appreciated. I'm assuming anything would be better than what is currently under the blazer, a '73, would this be a relatively simple swap? If so would/should I swap out rear and springs or just rear? Thanks [image] shocks seem to be nothing special so I deleted the pics.
