oil pump bolts

External pickup is nice. But i will ask,how is your motor mounted? What body? What exhaust? That set up works best with a plate and under chassis headers can have the hot exhaust pipes on top of your oil lines. Spool type motor mount will require major rework to clear a rear exit oil line. The adaptor plate between pump and block for a front exit line can cause clearance problems with early style mounts. And dont forget to loop the pickup lines up then down to keep the pump primed.
