Brackets for LS1 Electric Fans

Hey guys...I've got my LS1 fans and just ordered the harness from Nelson Performance. I wanted to see if you guys that have done this could post your dimensions for the top brackets you use. I don't necessarily need center-to-center on the bolts, mainly just the bracket dimensions.

I work for a sign company, so would like to have someone in the shop cut the brackets so I can be ready to install this when I get the harness in.

Thanks in advance!

C'mon...give ya a dollar...

Anyone???

I just want to get them cut so I can have them ready prior to the install. I don't have the necessary tock sitting around the garage, so I'd like to get them cut here at work. Any help would be appreciated.
