Larger PS pulley for LX Charger?

A member on the LX forum offered a kit to help reduce pump speed on early model LX cars. This helped reduce pump failure on cars used in autocross and track days.
He doesn't seem to offer this any longer. I'm wondering if anyone knows of a larger pulley that will fit an LX pump? I'm hoping that I can then fabricate a bracket to allow the pump to fit.

if you can find info on the diameter used and what you need bracket wise we could recreate the kit.

I think the stock pulley is under 5" o.d..
The switch was to a 6"o.d..
the bracket was to move the pulley, as it wouldn't clear with the increased size.
I'll see if can find a picture of the bracket
