    If you mean 'poly fitting' as in filling it with window weld or whatever; there's a completely separate replacement tranny mount that's made of polyurethane.

    Window weld it if you can't find something. I've used it for more important things with no issues.

    im thinking of cutting the dumbbells off a spare mount I have and welding a pair of large washers onto the holes for the bushings to act as solid bushings. i like the way the solid engine mounts feel so it's the next step i guess. lol

    yeah I am going full poly, but it turns out a buddy of mine has a CNC in his garage, I may start banging out some solid bushings if I choose to go that direction.

    That's how we did Altima Motor mounts back in the day. Holds up pretty decent. I just feel it is a bit of a bandaid

    after working in a body shop and watching the glass guy battle that window sealant every day i trust it as more than a band aid. that stuff is solid and stuck when it dries it has to be cut out and ground off. ill use it when its minor i wouldnt poly fill a controll arm bushing or anything like that.

    Having used it in a lot of different rubber bushings I'll admit that it will hold up very well if it's installed anywhere where it can be kept in compression all the time. I've done dozens of Toyota engine and diff mounts. The 'windo-welded' isolator bushings on my 87 are only slightly less stiff than the poly bushings that used to be available.
