hey guys i have a 1987 honda crx that i would like to convert into a convertible. from what i have researched, there is a version of my car that some company made. however, there was 310 of them made. so instead of searching forever and paying high dollar for a real one i would rather build one . so i was wondering i know how to cut the rear hatch off and stuff to make it into a convertible, what i need to know is how can i strengthen the chassis to make sure the chassis doesn't collapse in on itself?
