Wouldnt this be considered part of doing my homework? I'm asking for someone with more knowledge than myself to give me some sound advice. Is that cheating? I have measured the box. Like I said I'm not looking to buy new, therefor I won't be calling any manufactures. I fully comprehend that they don't have a shell specifically for an 88 MJ . Since i don't have or know anyone with a mazda,s10,dakota,ect ect. i can't just go measure their dimensions to match them up. Thanks for all your great advice.
