So I now have an MCD 7007. I bought a cabinet (L12 slant wooden legs to match my other cabs) and the 7007 seems to not want to slide in. Are the panloc brackets different for the 7007? this cab came with brackets mounted and so far I have just bought them off ebay and slid my C33 into one without a problem I had both my MR77 and now my MR80 in the same cab with same brackets, so it seems I need different ones?
