Does anyone know the bolt size that mounts the front engine mount to the crossmember?
Thanks

Exactly what Matt said. They are supposed
To be studs out of the motor mount. And you remove 2 Nuts.
However. 50/50. I have pulled out a few bolts too. If someone else has had your engine out,
They
Might have out a bolt in there.
A stud
And nut is much better when taking engine in and out and wanting things to aline.

The studs (not bolts) you need, GM part #390403, are special studs with a large shoulder between the two threaded ends. You might be able to jury-rig something with studs and a stack of washers, but I'd recommend checking with one of the Jims, or Cinnabar, or someone with a parts coach. Don't know, but maybe a Toronado would have the same parts. (My old 1980 Chilton's appears to show the same front mount on the Toronado).
