Raven9 Posted 5 hours ago Share Posted 5 hours ago Hey guys, 1978 RS600L /vin# RS686LST38380. Having trouble finding shocks. Fleetpride gave me a monroe# 66886 but they are a tick long with the plastic retainer on them. its a dump truck, and trying to square this away before I do the trans swap. Still deciding between a 9LL and 13. 502 rears. also looks like someone has removed the rear shock brackets on this truck and I did not due my due diligence when I bought it as everything was painted the same color under the bed so i just glazed over, looked for frame cracks but is double framed, never even thought about not having shocks, i know im an idiot lol. any help with the shocks is greatly appreciated! Thank you! Quote Link to comment https://www.bigmacktrucks.com/topic/75523-1978-rs600l-shock-part-numbers/ Share on other sites More sharing options...
67RModel Posted 4 hours ago Share Posted 4 hours ago Call local Mack dealer and give them your VIN. They should still have info for a 1978. Or call Watts Mack, the owner of this website. They have all the dirt on the old stuff. There is a Mack dealer parts guy on here a lot that always seems to come up with something. @The Heinz Quote Link to comment https://www.bigmacktrucks.com/topic/75523-1978-rs600l-shock-part-numbers/#findComment-575774 Share on other sites More sharing options...

The Heinz Posted 4 hours ago Share Posted 4 hours ago Old number 14QK2107, new number 85105666 which is available for order. They look like they're a Monroe 66891. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75523-1978-rs600l-shock-part-numbers/#findComment-575779 Share on other sites More sharing options...

Raven9 Posted 3 hours ago Author Share Posted 3 hours ago I’ve googled the Monroe, do you know if their front or rear? Or all the same? This is my first Mack so it’s been a lil frustrating on parts, I apologize for all the questions Quote Link to comment https://www.bigmacktrucks.com/topic/75523-1978-rs600l-shock-part-numbers/#findComment-575789 Share on other sites More sharing options...
