new car on the jig

I'm in Suffolk Va. There are a couple reasons for not using the double frame rail design. I feel they are for cars with a lot more hp, 1500+. They are hard to work aroung inside the car. The transmission in this type of chassis has to be removed from inside the car and handed out the passenger door. I "super class" racing the transmission and converter see more action than anything else and need to be easy to r and r. Then there is the weight issue. I know there are a lot of bars in there but I am trying to keep them to a minimun compared to current chassis out there.
