need a source for "oversize" sphinx glides

[Boulder Bob]

My 90's Dual Professional has 1 1/4" diameter sphinx glides, 1/4" bigger than most Fender amps. One came off and is lost. Anyone know where I can get these?

Thank You.

I have some NOS Peavey sets here that are 1 1/2".Not what your looking for but they are packaged sets and there cheap.
