Kyosho RC Shock absorber spring seat for 8mm body shocks

This is a spring seat for the old-fashioned 8mm body coil-over shocks kyosho used on classic RC cars from the 70's and 80's. I am restoring an 80's vintage Kyosho scorpion, and needed a few of these for my rear shocks, but didn't want to bother trying to find them on ebay or whatever. Pretty simple part, so measured one I did have, and simplified it a little bit and made compatible part.
