    This item was brought up in another thread, I was trying to figure out when Mopar first started using this. Part # 2951590 big block cable # 2951589 small block cable, 2951592 big block spacer, 2951593 small block spacer, 2951594 bushing all, first shows up in the 1969 parts book section 9 (V8 engine.) I don't see it listed in the 70/71 parts book but it must have been available. It shows up again in 72 same section but as a set of brackets with new part numbers. Anybody have a 70/71 with this part? I think it was available as part of the trailer towing package as well as Police /Taxi. IMG_1866.JPG

    I had a 69 Monaco 383 with that cable. My 70 Fury conv does not have it.

    Could it have been a re-call item/bulletin?

    My '70 Fury doesn't have one, but it sure could have used one when I broke the left motor mount and my air cleaner screw put a tit in the center of my hood!
    :rofl:
    When we "raced" we bolted a short length of chain from the exhaust manifold to the frame.

    After busting 2 driver side motor mounts in under 12 months, the first year I owned Mathilda, I wised up and chained that 383 to the K-frame just so. Haven't had any trouble since then.

    A big of historical information on these things, from the Chevy realm of things.

    The "big news" was that when a motor mount failed on a later '60s Chevy car, before they started to use throttle cables, when the lh mount might fail under acceleration (as in moving away from a stop sign), the throttle linkage could bind and cause problems. Hence, their "Motor Mount Restraint Kit", which was a factory recall situation for many later '60s cars and pickup trucks. We got it installed on our '69 350 V-8 pickup. In that kit, it was a new mounting bracket and the new inter-locking motor mounts, which were put into regular production after about 1970.

    In the 1980s, I bought some obsolete parts from a Chevy dealer near me. In that "stash" was about 40 boxes of the GM Recall "cable kits". I laughed when I saw them. But it was even more amusing when I took some to the Pate Swap meet and a guy with a restoration parts business started drooling over them! It was "Eureka Moment" for him, his eyes got bigger when I told him I had more. LOL Later that night, he came to my shadetree shop and filled the trunk of his rented Mercury Tracer with all of the remaining boxes of the cable kits. He laughed, to his frined, that if his father had told him he'd be doing this, he would have called him "Crazy". Yet, here he was doing it. He got his "treasure trove" and I got some $$$$. All was good.

    When the lh front mount degraded on our '66 Newport, the top of the a/c line from the compressor would touch the inner hood structure. I got some stiff electrical wire and made my own "restraint" vis the power steering bracket and nearby stub frame rail. That, plus a bit of restraint, worked until I could come home from college and get a new mount installed.

    GM/Chevy tended to get all of the publicity for the engine mount issues, even some lawsuits, as I recall. Many manufacturers put new "fail-safe" mounts into production as a result, with little fanfare, to replace the earlier-design mounts.

    By comparison, the Chevy recall kits were much more substantial.

    Enjoy!

    Likewise to you! I'd agonized over whether to spend scarce coin on polyurethane mounts, or sweat on custom modification of the $3 asiatic rubber + dubious ferrous alloy mounts. But the BEST investment by far has been to leave well enough alone on the latter sort of insulator/mounts and to deploy that bit of tow chain to hold the 383 fast to the K-frame, leaving just enough slack for the rubber to absorb vibration, but not enough to permit the engine block to rise off the frame, tearing the mount as well as damaging stuff like the charging stud on the alternator, the air cleaner and such.

    If I had a decent tension scale, I suppose I could measure how much tension I put on the chain when bolting it to the frame or cylinder block, just to quantify what seems to be a good medium tension for future use. Perhaps I will obtain some such "fish scale" before replacing the motor mounts again. I just pray I won't need to until I replace the ENGINE in a couple years. (hopefully)

    Gaudate!
