????What is center to center size of two bolt mounts were they bolt to frame?;I've got one bolt Y mounts that I'm using right now,but this is a hotrod and would like to also drill the mount plate for two bolts to frame just in case I ever need to replace them. Thanks if anyone knows the spacing on frame side/not block side.

I'm just trying to save some time down the road, if ever I need to change to two bolt vs one bolt motor mounts[harder to get at times],was thinking if I drill the frame plate now for both.

Bat:

The studs are 2 5/8" apart, center-to-center. I don't have a single stud mount to compare the orientations of the bolts, but the distance from the upper edge of the steel plate that the rubber is bonded to to the center of the upper bolt is 3/4".

Thanks,that put the one bolt dead center between them,very good,now I can just drill the two extra holes,they don't show anyway,but if there needed,no extra work this way.
