you can look for lower body posts or do dome custom Dremel work and lower them yourself.I've made custom body posts and done some cutting of original posts relocating body post holes when i wanted a certain look...I'm a firm believer in aircraft stainless steel safety wire with the pliers to use...
to stop body from catching air i always put 4 holes 1" in front windshield and the cut out fake fans behind rear shock tower. can't make your own belted .gota buy them
