If you use the original hole on the automatic mount, the engine will sit askew and you will be more prone to axle breakage.

To cure this, there is a dimple on the automatic mount that most people use as a guide to drill their new hole to mount the motor and transmission.

Here in this post I will show you guys how to modify your mount step by step to alleviate this situation.



here is your mount. the first thing that we must do is remove that 19mm nut that was welded onto the mount from the factory.



To remove that nut, you must get a breaker bar with a 1/2" drive.



Now find a 19mm 1/2" socket.



with little force, the welds on the nut should just shear off like nothing.



alright so here is what we have to work with.



the dimple above the original hole is the exact spot that we are going to drill the hole. There is much speculation about the exact position of where the hole should be, but I have spoken with a few people (skaterdudz02 and many others) that have used this dimple as the template for drilling the hole and they have had no problems thus far.



to drill the new hole I used four drill bits to make a 1/2" hole in the mount.

I started with the 13/64", then the 5/16", then the 3/8", and lastly the 1/2" bit. The diameter of the bolt is 1/2", therefore this will be the diameter of the hole we will be making.



so now get to drillin' like youre sarah palin! :lmfao:



I slid the a bolt from one of the other mounts in the original hole to use as a reference to keep the bit as aligned to the original hole as possible.



and some more drilling..



and voila! we are done! :thumbsup:





I used the original nut.



the alignment is really close to the original. pretty good for eyeballin it. :D







I hope this helped you guys! Now go do yours!
