38,
I don't know if it is like my 46, but can you take one of the rubber spacers out from under the radiator support down by the engine mount? I thought there were two and you could adjust the height by removing one. If you lower the radiator support, you would give yourself that smidge of room you need...
My 46 had one spacer when I took it apart and the replacement part came with two rubber spacer/vibration pieces (sorry..too lazy to look em up to see what they are called..)
