Ok, so I'm sick with what I assume is the black plague, and I'm probably going to die, but I managed to get out of bed long enough today to check my current set of 89tm rockers:



Pass front 2.183"
Pass rear 2.040"
Driver front 2.036"
Driver rear 2.150"

All spring clips seem to have 0.100" between the rocker arm and roll pin
Bumping to get the brain juices back flowing. Originally I was going to subtract .025" from your measured dimensions, for the clearance needed. Whats this 0.100" rocker arm to roll pin? Does this affect the spacer length? struggling to picture it

I think I have a raging semi going.
Yup needed to take a break yesterday and banged them out, PM sent.

Not about the raging semi... Address to send these things.

Probably take me a couple days to get to the post office

I just finished installing a set of these on my truck. My dad made them on his lathe... I've yet to test it out on the freeway. I'll post updates and pics after I put some miles on it.

Didn't want to break hiatus, but worthwhile update.

I screwed up the rocker shaft measurement, so despite Farmer's best efforts, the ones he made did not work, 100% on me.

Had a machine shop in Maine crank these out. Will update when my engine is back together (currently a bare block).

So what size is the spacer/washer at the ends of the rocker shaft? Were shims necessary?
