Alright, I took a look and it's the cable going to the right rear that broke (rusted through), right at the junction where it attaches to the front cable.
I've got the following at my disposal:
1x 10 ton bottle jack.
2x 2 ton jackstands.
Small wrench set
Small socket set
Various other household tools (claw hammer, screw drivers, pliers, etc)
And I'm off work for the next week. I know how to change spark plugs/oil and such, but this seems to be just a level beyond that sort of thing.
Do it myself or pay a professional? Any NPORA members in NoVA that would care to lend a hand?
