Thanx Ronnie, I was afraid there was a special reason for the test light.... I'll have to find an equivalent at a different store (since RS is defunct)....
Thanks, Ronnie. My plan is in fact to wait until fall/winter . Not quite sure I personally will tackle the job at age 71 (vertigo) but will certainly read all about it beforehand on the ROJ (the ROJ is the best thing since sliced bread in my opinion). I always like to be fully educated on a car repair before handing it over to a mechanic.
That's not a bad job. Good wintertime project so you don't have to get in a hurry. Instructions are here on ROJ and I have a ton of photos on my computer if you need them.
