Motor Mount Bolts

[CruisinMT]

my 67 F engine bounced out two of my front bolts that hold the mount to the engine. I need some replacements does anyone know the size and thread pitch of these bolts. I should probably use locktite I'm guessing when I put these back on?

I replaced mine with standard grade 8 hardware (1/2 inch IIRC) and nylon lock nut. iT's been several years w/ no issues.

I believe the stock had a castle nut and cotter pin.

Mine is A 78, not sure if that makes a difference.

Thanks but I need the bolts for the bracket i guess. It has three bolts in it. THey connect the bracket to the block.

I believe they are 10 x 1.25 (14mm head) but the best way is just pull one from the other side & check. Who knows what was in there before they dislodged, so you better make sure you have threads left in the block. Most of the hardware I've encountered for mounting brackets or components to the block are all the same diameter & pitch, one of the thoughtful things Toyota does. If you haven't changed to the later flat rubber mounts, now might be the time. Torque them properly & you won't need locktite.

10mm 1.25pitch x 25 mm long. They are supposed to have a lock washer, but of course blue loctite wouldn't hurt.

thanks guys, threads are find i think they just wiggled out. New 2.5" Rancho Lift makes for loose parts I guess.
