Re: Bolts for battery tray? Size?
Two different size 5/16-18. They're shorter on the LH side to add clearance from the radiator.
The battery box mounts to the core support’s RH rail using three (GR 5) 1/2" hex recessed head tapered bolts with spin washers. The bolt threads are 5/16-18 x 5/8”, and the heads are stamped "ELH".
• The battery box mounts to core support’s rear wall using two (GR 5) 1/2" hex recessed head tapered bolts with spin washers. The bolt threads are 5/16-18 x 7/8”, and the heads are stamped "E". The box’s LH side has a fixed J-clip for the radiator overflow hose, though a retainer clips onto some boxes. The box’s LH side is stamped 3886786.
