distributor nylon shaft collar where to buy??

I was able to find a supply of steel collars with a set screw to replace the stock nylon piece. I bought 2 for my distributor. You can use one at the bottom of the distributor shaft against the drive gear to prevent erratic timing signal from the drive gear wanting to push up the distributor shaft. I will be filing a flat in my dist shaft for the set screws.

Anybody interested in a set of these PM me.

$5.00 each collar plus USPS shipping. i will combine shipping no prob.

Thanks
Matt
