Classic/Antique Car Repair: Motor Mounts, 1971 oldsmobile cutlass, oldsmobile cutlass

Question
Could you tell me what kind of motor mounts and frame mounts I need to mount a 396 engine which came out of a 67-68 Chevelle into a 1971 Oldsmobile Cutlass which had a 350 in it? Mabye I need to get adapters and then drill different holes into the frame?  Could you help?  Thank you so much!!

Answer
First make sure you have enough clearance with the exhaust attached for it to fit without having to modify the crossmember. I would look at the mounts that came out of the Chevelle and see where they hit on the frame. The perches should be interchangable, as long as the firewall clearance allows for that.
