Coilover conversion brackets
 

I've been reading on individuals who custom built brackets to convert front to coilover springs, but this was the first I've seen from a pro-shop.

1) Does anyone know if these conversion brackets are sold by any other companies besides Ridetech?
2) Does anyone know if this type of bracket can be bought without control arms?
Thanks
