I had the distributor apart to inspect it and to install a new pickup coil and ignition module in my '91 350. What I found was the shroud was bent out of shape and what looked a lot like bits of rock in there. Most likely that was material securing the magnets in place. Turning the shaft by hand it was catching on something. So after disassembling I found the coil retainer looked like half of it was missing and gone. It looks to me like the clip may have broke in half and jammed against the shroud then gouging into the magnet wheel braking some of the material securing the magnets loose. That's all I can figure. I straightened the shroud and cleaned up in there real good and reassembled with the new coil and module. This is an 82,000 mile truck and the shaft is nice and snug.
A couple of the magnets have bits missing but it runs pretty good. How critical is the size of all 8 magnets? I will most likely replace the whole dist but am curious how these work.
What is the preferred brand of replacement distributor for our trucks? Budget minded of course for this all stock, original truck.
Appreciate your input.
