Prothane motor mount issue
#1

In attempting to install the driver side Prothane motor mount into the shell, it does not seem to fit properly. I know I have the right parts, and it is oriented correctly.
The mount seems too tall, causing the shell to bow when bolted together. I did not finish cranking down the bolts in the pictures, but you can see that there is a good deal of stress on the top clam shell. With the larger bolts removed and smaller bolts tightened down, you can see the huge gap that remains.
Have any of you experienced this? Am I making too big a deal of this? Possibly the mount will compress more when bolted to the block? I'd like to get this figured out now, since getting to the motor mount later is a PITA. Thanks.

Mine were the same way.
With all the bolts out I clamped mine down in the vice so it tightened on the mount squarely, then put all the bolts in and torqued them.
It looked okay after everything went together. I think you definitely need to tighten both sides evenly or the mount will be bulging out to one side.

dont freak out if the bolt that slides through it doesnt want to go through either. I thought something was majorly f'd up but they are just so much tighter/harder you almost have to thread it. Makes it a major PITA when you get it all lined up and the engine wedged the right way and then the bolt just laughs at you and goes in half way and thats it.
Your probably already past it but if you leave it out and in a vice and just test fit them it makes life easier once your in/under the car.
