I'll try calling SPL again I guess. I e-mailed Kuah asking about their version of the upper arm and he told me that the investment to make them is too high. He didn't tell me of any other options, but maybe I'll call to make sure. Ordering from HPI looks a little scary. It looks like they cost around $484, then how much would shipment be? Wouldn't it take forever to get them? Thanks again Jack H '92 n/a
