Need two new rollers ASAP

A handy person from California says:
There are no markings on the part. Is it possible to get basically this model, in terms of thickness, but with two wheels? This is a really heavy glass, patio sliding door. I think the previous guy put wheels on that are too small. The wheel is 1.25" diameter.
Also, I'd like to ask for expedited shipping.

Take a look at SWISCO part 81-039,sliding patio glass door roller, and compare the dimensions. This roller assembly looks similar and has a larger 1-1/2" diameter wheel.
