Super Stock Seat Brackets Anyone??

Hey all,
Lets see how much interest there are in these...I was lucky enough to have a fellow member send me the detailed dimensions, so I drew them up in SW real quick. Tell me what you think. According to the dimensions, the brackets are a mirror image of each other...is this correct? Tell me what you think. I personally dont like the placement of the holes, and would put a hole in the gussets, but this is how the original's were, so this is how I will build them. Hoping to have a quote by tomorrow, if not Monday for sure. I'll probably do lots of 10 at a time.
Thanks in advance.
