leathermang,
I've been through that tire thing...vibrating tread on a couple front raintreads, I then transferred them to the rear, and the rear(now on the front) became warn and loud..... talk about quadraphonic sound!! unbearable for a while and i was glad when they wore out. and you're right I think its time to pay attention to the undercarriage and some coating. .... 240 is automatic. I'm presently working on a project car... '83 300 turbo installing a 5 speed manual. about mid way through project...i.e. auto trans out, rr main seal replaced, bad motor mounts fixed, new trans coupled and everything sitting back in place among other things. garage floor is cold about now. cheers, mark
