quote 65beam:

keep in mind that you have no metric bolts on an alpine.at least i have never had one with metric .

Huh? Are you sure? When I’ve gone to the hardware store to buy new bolts I bring sample bolts w/me. Some sizes/threads matched up w/SAE and some matched w/metric, they then bolted right up, no sign of crossthreading. Even when I’m removing some bolts, some I have to use SAE sockets/wrenches and some use metric, only time I’ve ever used a 16mm socket, has been w/this car, I’ve also been using metric wrenches on the hydraulic fittings.
