Thanks to all that helped me. If it wasn't for your suggestions, I would not have kept pestering my mechanic. Final total - 340.00 for the CAT. I realize I could have got it cheaper myself, but now I get my truck back tomorrow! I can return the match box on wheels that Hertz calls a mid-sized car! I'll let you know how it is running tomorrow. I got front & rear brakes too. I haven't stopped in a long time! It will be great to get my boy back after a week of the rental! I also noticed every truck on the road this week. I'm jealous and want mine back - I get a lot more respect. You wouldn't beleive how many times I get cut off just going 5 miles to work in the little car.
