rear subframe question
 

I'm missing the rubber bumpers (bushings?) that go between the rear subframe and the chassis. They are no longer available from Mazda. Anyone know a substitute? Or have one that they can measure so I can try to replicate? Picture attached if it helps and the part number is FD0134610A. I ordered replacements from nengun.com, but I assume they won't actually be able to ship. Picture here:

Also, if I ask too many questions, you guys feel free to tell me to shut up. :-)

Oof... in all the years I've been on this forum, I have never seen that before...

I'd suggest posting in the Marketplace. Also pm djseven, tomsn16, fritz flynn or others who have parted a car

The bungs are plastic from memory, probably easier to turn some nylon to size than find them, may need to buy a complete subframe to get them otherwise - which may be no bad thing if you've got the early unbraced one as shown in that fiche!

Had at least 4 subframes around here and never seen them fall out either, your car hasn't had those "solid" Japanese subframe locating bushes installed by chance?

I could print them in nylon--I just don't know what to print.
