    I need some help finding the clutch bushings specs for a 1g clutch pedal assembly. There are 5 bushings total, 2 are the same. @Brando_DSM used to make them and gave me the specs he had, but I need all of them to get some new ones made (or ideally find some pre-made that match).

    https://www.dsmtuners.com/threads/1g-dsm-clutch-pedal-assy-bronze-bushings-all-5.520182/

    -Left clutch rod bushing
    -Left and right brake arm bushing (same size)
    -Right clutch rod/z-bar bushing
    -Clutch master cylinder rod bushing

    I need the following for each bushing:
    Inner Diameter (ID)
    Outer Diameter (OD)
    Overall Length (OAL)
    Flange Outer Diameter (FLOD)
    Flange Thickness (FLTH)

    I went ahead an ordered all the bushings from Extreme Psi. I'm going to try measure/reverse engineer the plastic bushing and find bronze bushings to replace them. I'll have a machine shop make them if needed. I'll post the results when I get them.

    There may be a small difference between the plastic and the metal ones made. In my experience the plastic compresses while installed. I was planning on making my own eventually. the best way is to pull the clutch pedal assembly and measure everything. or get a second one to do the work on. :thumb:

    OK I got the OEM plastic bushings from @extremepsi Here's my measurements, anyone know a place where I could buy off the shelf brass bushings in these sizes? If not, I'll hit up my local machine shop and have them make them.
