Randy, several of our members have used Interstate Metal and have found them to be very helpful. It's possible Interstate MAY want you to send them a small sample of what it is you're tryng to replace. I would think that would be the best course in order to make certain you're getting an exact replacement.
Once you get exactly what you want, would you please come back and post some more info...like model(?) number and price paid. It may help a Burro
owner in the future.
Oh, and glad to have been of service...that's what we're here for
