No, the older cars used the sandwich style motor mount, in 73 they switched to the spool mounts....
You will have to get a set of 73 and later 318 mounts... They should not be hard to find a set of 318 spool mounts, I think you can buy them at the parts store - NAPA... If not, post a wanted ad here and someone will have a set...
Beware: 340/360 mounts are different from 318/273 mounts, the driver's side mount is 1/2" different - just enough to piss you off...
