Bobble Mount Bolt Size??

Ok, I need the size length thread pitch of the bolts for the bobble strut mount. The part that mounts to the engine or transmission (I forget which) that receives the shaft of the bobble strut.

I called my local "5 star" Dodge dealer and he said It must have been modified because there are studs coming out in the picture he was looking at.

For the car in my sig.

Thanks in advance.

There are two long bolts holding the bracket to the transmission on a 520 and I would think 555 is same. Head size takes a 15 mm socket I think. Just had them out while changing out k frame but didn't happen to measure. The bolts are pretty long though.

thanks for the info mike!!
