Mounting seat rails to the frame vs the floor

Has anyone done this and if so, what is the best way?

Contact Eddie Janis via the registry, he can help you!

Thanks Jim. I'll give it a try.

I did it...I placed two rails across the frame tied into the base of the tunnel...it makes a very solid mount, downside is that it raises your seat base up 1-2 inches..

Michael: How did you attach the rails? Do I have to figure out how to get to the inside of the center tunnel to put a nut on the bolt? Also on the outside did you bolt all the way through the frame?
thanks

welded to the tunnel and the frame on side of the pan...my car has heavier frame in the body than most cmc's..

I was afraid you were going to say that. Welding is a little beyond my scope. I may have to come up with a special bracket.
