Mine came in about the time you installed yours and you aren't kidding. The instructions leave a bit to be desired. I will be installing mine today and I wanted to thank you for posting pics. They answered some questions I had.

Glad my post helped! feel free to shoot me a PM if you have any more questions!

You can use the motor mounts to lower the engine 1/4 inch but spacers are included to put the engine back in its original location as well.

I want to know if the mounts change the engine position at all from factory? any NVH IMHO with this mod is a plus because it is one more direct connection between you and the car....peace out

Sounds like an awesome ride! unfortunately the car is still on stands so I don't know about any NVH yet, but I have the same opinion as you. The engine sits in the same place unless you opt not to use the 1/4" aluminum spacer, then it will sit 1/4 inch lower than stock. I opted to use the spacers because I don't want the header collector to be too close to the ground.

Just wanted to let you, and anybody else, know I put them in with minimal difficulty. There is noticeable harmonic vibrations transmitted from the motor at idle but nothing irritating. Hardly noticeable at speed. My wife rode with and she didn't notice. Then she drove it and didn't complain or mention(yet). Shifter is rock steady-of course prior mount was broken. Feels a little more responsive.

If I had to do it again I would reverse the locations of the long and short bolts from what the instructions say, which, from your pics, it appears you did that already.

Good to know.... Mine rocking with its cam is a lot more than stock as are all built motors in about any car.....And someday the stock has to go.... so its a wonder if stock is a lot better with the vibrations compared to stiff poly....
