Ur mounts are gonna have to be custom. Nobody makes mounts for D16A1's, at least not that I've found. If possible, you should keep or get the mounts that came with the D16A1 so you can adapt them into ur hatch, or use them as a template when fabricating your mounts. It might be worth ur while to contact a welding/fabrication shop to get an estimate if ur not able to weld urself. My stepdad owns a welding/fab shop and he charges out the ass on jobs like these. Good Luck!
