I told Howard that it would be a problem a year ago when he showed me the pics. If your frame guy is good he should be able to salvage some and not need a whole lot. If you need anything let me know I get a good Mazda discount.
I have close to 1500 in parts sitting on a shelf waiting for a the motor for the 7 which should be picking up in the next few weeks.
Have about 2k in the chassis which includes getting it from South Carolina getting it cleaned up and caged. Plus I still am going to paint it but thats cheap
