Dia-comp roller parts help

[scooter01]

I picked up a set of Dia-comp rollers from Spoke this weekend. Spoke wants me to get back in shape so I can keep up with him!

I need to replace the belt from the rear drum to the front. I have searched on the web some and have not really found anything that might work.
My guess that theses are 2 1/2" drums. Anyone out here haveany idea where i might find a replacement belt?

Call first Larry Black of Mt. Airy, MD cycles than Mel Pinto of Mel Pinto Imports, Va. This might be a std. belt so nothing magic about it. Take a string and get a measurement.
