So I will be installing Prothane motor mounts this evening, and I seem to have lost the bolts that are used to bolt the clamshell around the new mount. The directions say the bolts are 1/4"-20 and 3/8"-16 but does anyone know how long they are supposed to be? I hope when I get everything apart it will be easy to figure out what length will work but any info to ease my mind would be greatly appreciated

 

length, about 1" or 1.25, you can always cut em down if they are too long.

and the threads dont matter, just as long as it fits in the holes, and you have a matching nut for it

 

I kind of figured that, once all the pieces were off it would just be a matter of making something work.

 

i didnt use any of the small bolts they supplied..........i dont see what they were for at all.........i just used the zip ties to hold the clamshell together, then the 3 large bolts to bolt the whole thing onto my k-member.


btw, be careful you dont jack your motor up too high.

 

ur supposed to use the bolts to hold the drivers side together. i dont see how you could get tie wraps to hold the drivers side together, as the mount is oversized on that side.

use the tie wraps for the pass mount.

 

that makes sense.......i didnt do the driver side
