I'm installing a 7.3 diesel in an 89 F-250 4-wheel drive 5 speed. I need the bellhousing bolts and motor mounts. My local Ford dealer was unable to help. Anyone know where I can find these bolts?

 

Try napa for the engine mounts and i believe the bolts to the back of the engine are 7/16"

 

i might be wrong but i think they are 1/2" grade 8

 

Thanks for the responses. The bolts are 1/2 inch. Don't know the lengths of the bolts. It appears two of the bolts will be fairly short and 4 will be an 1-1/2" longer or so. I don't want the bolts to bottom out or not have enough bolt in the block. Should these bolts have all threads or threads up to a certain point ?

 

Threads to a certain point

 

i had to replace one of mine i got a new one from tractor supply just can't remember the length

 

im also needing the dimensions of the bellhousing bolts. i dont mean to thread hop but im picking up a project that i didnt start and the bellhousing bolts are nowhere to be found. i know the top 2 bolts are smaller than the bottom 4. thanks in advance

 

I can't find missing bellhousing bolt for my 01-ford-ex. is it 6 or 8 bolts. I have 2 long bolts, and 2 shorter bolt.How many bolts are there in all?

 

Just measure them mate. Stick a straw or something in the hole, cut it off flush, measure that, and buy bolts that are the same length or slightly shorter. As far as bolt material goes this application is not a high stress one in that even low grade bolts would easily handle the stress. Go for grade 8, and if they are a few threads shorter it's not going to matter, just make sure they are tightened to the proper torque. You could also take one of the other bolts out and stick it in the hole and see how long it is.

If you are at all experienced with wrenching, you will be able to tell if they are bottoming out i the hole and stop before they cause damage. If you aren't experienced enough to tell that, please don't continue the project.
