All should fit sometimes with a little sanding, etc as how the fuse is built will detemine how easily the firewall sits in the tabls, etc (if there are alignment tabs used)
How the motor mount fits, assuming it's not hardwood rails has no relation to how the firewall is intalled. It simply mounts to the front of the flat firewall. You have me curious now.. I'm going to open mine up and look at the plans... brb
