That truck is awesome,the mounts should be the same.I replaced a poly 318 with a LA 318 in a 66 Coronet 500 and used all poly mounts and trans.Hope this helps...............................Jeff...
I had a 98 with a 5.2 and 3:92 gears,Ran like a scalded dog..............Got about 10 mpg no matter how you drove it................................................Jeff
