I have a 6-speed with an SPD crossmember. I have a polyurethane mount, which is letting a lot of vibration through out the car. I decided to buy an LS1 tranny mount too ease the vibration at 75mph. Heres the problem..... .....The mount is causing the crossmber holes to be about a half inch off on one side. Is enlongating the single tranny mount hole in the SPD crossmember ok? What about the frame bolt holes too? I dont need much. Its stretching and binding the mount so its pretty close.

Car is still on jack stands.
