    I have looked around but can't find this specific information.

    I'm dropping a 360 into my '73 Duster and had to replace the K frame. It had a '67-'72 style K frame that some PO cut up one of the motor mounting pads. The K frame I was able to get is the newer (and correct) style K frame using spool mounts. I ordered some motor mounts from O'Reilly's, both left and right side. The problem is that the neither of the new mounts come close to fitting the driver's side of the block. The mounts are noticeably different but are the same width. If I bolt the mount in front of the ears there is a gap of about 1/4". If I bolt the mount in back of the ears there is about 1/2" gap. O'Reilly's web site does specify these mounts for a 360. Do these type mounts bolt in front or rear of the ears? Is there supposed to be a 1/2" spacer on one of the bolts?

    The problem is the same no matter which mount I put on the driver's side.

      I just measured the distance, cut the mount, bolted the 2 halve on the motor and welded the mount. Easy when it' on the stand. No washers needed.

      Here is how the correct mounts should fit, no washers.

        The new mounts (the ones I'm having a problem with) are the spool type if I'm not mistake. Anyway, they are the correct style for the new K frame.

        Thanks!

        Not on the drivers side, I might have an extra 318 spool Mount.
