68 K15 Motor Mounts

[r8e1d]

When I bought the truck it did not have a front crossmember in it just some welded up perches. I bought a 4x4 crossmember and small block perches from a vendor here and installed it. Figuring that it was stock and LMC sells "stock" mounts I bought a set and tried to install them. They do not fit, the motor sits to high and the bolts will not line up. Maybe I installed them wrong, if so due tell. So what motor mounts work with the stock crossmember? Tried searching with no luck. I have found mounts that look like they will work (Energy Suspension 3.1156) but i don't want to waste more money buying the and ending up in the same place. Truck has a 350 crate motor in it.
