    I don't have a full upper mounter mount to play with that inst on a car. Can the rubber bushing be removed and a poly Sheet/block be cut to size and put in its place?
    I'm guessing the upper two bolts are molded into the rubber or the rubber molded to the mount?
    I was thinking of getting a block of poly and cutting it to size to stiffing up the mounter mounts.
    Any one have an tips or thoughts on this?

    I think you can buy two part urethane mix to replace the rubber in a worn out mount. Probably the simplest way to prepare the mount would be to burn out the rubber in a low camp fire or woodstove, then sand blast it. Avoid getting the metal too hot though, or it will be damaged.

    I just replaced my upper mount with an Anchor brand unit, and the improvement was immediately noticeable when shifting or getting on and off the gas at low speed.
    Unfortunately after a week the mount is as bad as the OEM one I took out.

    Casting a new one wouldn’t be a best option. The stock rubber bushing on a first gen is more or less wedge in between to plates of steel. I would think cutting one out of a sheet/block would be simpler.

    my concern is if the stock bushing is molded to the mount and the bolts might go through it. Obviously I need it off to make the new one the right size.

    I wouldn't cast it either, in the 84-90 cars it's just like you said: a flat piece of rubber sandwiched in a gentle "V" shape. I always thought one could replace the stock one with a chunk of semi-truck mudflap and drill 2 holes for new bolts, if you can find a source of 3/16" or 1/4" sheet/plate polyurethane or a similar hard plastic that's the way to go and just drill 2 holes for 2 bolts of your choosing.

    But then again, that's so thin why not just go metal-on-metal? Even if you have to use an additional block of aluminum or steel where the rubber would be to get the motor angle right. That thin sliver of rubber in the stock format doesn't give much flex anyway, just somehow sags over time when it's deteriorating.....

    The 81-83 cars however get NASTY over time because they use a more traditional rubber mount utilizing a rubber block with a steel casing and steel bolt out the bottom with bushing through the center of the rubber inner.

    Oops, I was thinking of the second generation cars. So disregard the earlier post.

    I was thinking of going solid, but I'm not sure how the rest of the car would take it.
    Has anyone does that to a 80s escort ?
    although TBH 95a poly would be just about as hard as a solid mount wile still having some give.
