Motor mount questions

You can use the drivers side mount from your 318 on the 360 by making a spacer that is about 1/2" thick to make up the difference in the spacing on the 360. The passenger side is the same between 318 & 340/360.

If the mounts on the 360 are orignal mounts they are likely spool mounts and won't work with the 67 K-member.
