How to replace advance weight pins in distributor?

[camrycurt]

Hey guys,

I've got a question about replacing the advance weight pins in a stock GM 6 cylinder HEI distributor. The PO upgraded my 1970 C10 with a 230 inline 6 to HEI with a 6 cylinder GM HEI (with the separate coil).

Last weekend I finally got around to pulling the cap and rotor off the distributor to have a look around and found that the bushings on the advance weight pins were long gone and the weights had been flailing around in there for goodness knows how long. As a result, the pins are worn about halfway through and the holes in the weights have been worn into ovals.

I was already in the process of ordering an advance curve kit so I'll have new weights, bushings, etc., but I'm wondering about replacing the worn pins. Rockauto sells the replacment pins, but it wasn't clearly evident to me how they're fastened in - it looks like they just slide in.

Has anyone replaced the weight pins in a stock GM HEI distributor and can tell me how the pins are held in? Is it just friction? Do I just grab the old pins and pull? Do I need to completely disassemble the distributor to get them out?

Thanks so much for any help.
