Then just force the subframe on with a jack, which will compress the bushings inwards. Done, and it ain't going anywhere. You can follow up with some WindoWeld if you want to fill in the voids.
I did this years ago. Tons of people have used the same method in competition cars as well. Sounds hack, but it's proven. I refuse to spend a billion dollars on aluminum bushings that will make the car loud and crappy, as well.
So dan, realistically I should be able to bolt the subframe in place, after gutting the original bushings, then bolt the rest in place, and fill the voids with the liquid poly, without worrying about it being off center due to the locating pins ?
