used car, high mileage. i'm with you there...hard to justify sometimes spending $250.00 on a part for a car i'm not keeping, or on a car worth $400.00 no matter what's done to it.
so i hit the junkyard for that stuff, but i would think that motor mounts are either:
**already missing.
**a nightmare to remove from a junkyard example.
but a lot of good oem parts are stupid cheap on eBay...
a good example: our local junkyard sells a brake caliper for $17ish out the door, customer removes it. i went last week to grab one, and it was messed up and the wheel lugs were stripped out so the wheel wouldn't come off. only car there where the part would work.
i went on eBay, and got a rust free brake caliper shipped out of tennessee for $20.00. with a 6 month warranty. and perfect pads to boot, which i didn't need.
so check eBay as well. avoid northern rust-heavy states like pennsylvania.
i have to add, though...i have advance auto lifetime cv axles in my 1988 crx. 5+ years, no issues.
and my advice may suck. i want to lower and turbo everything i drive, and run infiniti wheels on my honda and mustang rims on my lexus.
