FridgeFreezer Posted September 4, 2022 Share Posted September 4, 2022 Per the title really - the 127 has a Gemmer 6-bolt "heavy duty" box and I'd like to source a spare arm for it to rebuild the ball joint, but it's not entirely clear if they share arms with the more common 4-bolt boxes? RTC6398/RTC6399 is the part according to LRWorkshop (not sure what the difference is?) where the 4-bolt flavour has a different part# so there's clearly something going on.

Retroanaconda Posted September 5, 2022 Share Posted September 5, 2022 My understanding is that the Gemmer and Adwest boxes have a different taper/spline for the drop arm, and so are not compatible. A 4-bolt Adwest will take the same arm as a 3-bolt Adwest. But a 6-bolt Gemmer is different. However the 4-bolt Adwest and 6-bolt Gemmer both take the same (metric) pipe fittings, whereas the 3-bolt Adwest takes different (imperial) fittings. 2 Quote Link to comment Share on other sites More sharing options...
