Anybody know anything about these?  Info?  Make?
I asked about who makes them and why they would not fit an Interstate:

Thank you for your interest. We have been selling and installing these shocks in our service department for over 30 years. They are our house brand which are specifically manufactured for us. They have a black painted finish. Unfortunately, they will not fit the Valkyrie Interstate model because the mounting eyelets are different. Also, I do not have any information on Progessive shocks.

they look kinda like the progressive 412  ones I had in chrome that were 11 inches made for a VTX  from XCHOPPERS.COM they have other models not made by progressive but look the same

I put in the I/S in on the fit table on the 12.5 ones on E-bay. It also says will not fit I/S. beats me.

Since there are no shock fitment differences between Valk models, I would not trust them to know WHAT they will fit.
