Can you post a photo of what you have? I'm thinking they might be Asiatam. I have a set of those at home so I can check them after work, But I don't know if I can measure the distance between swing arms without removing the roadwheel, and I'd really rather not do that.

Here's another case of that damn ocean being mean to us. I have an HL panther Lower Hull with Swing arms and road wheels attached that I would be willing to just send you for free but postage would be more than what the part is worth.

Sorry I can't be of more help.
