[...] Now I just have to convince myself that it is alright to spend $328 per tire plus taxes and shipping for redlines [...]
As I mentioned before, JEGS has $100 off coupon and free shipping. So, it's $303 per tire, plus taxes, and free shipping. It's still a massive punch to the face, but you get to skip the knee to the gut when you're keeled over from that punch.
My wheels are 14x6. Three are from a 69 Chevelle (K 19 10 YW) and the fourth is from a 68 Chevelle (K18 5 7 XB) -- they were on the car when I bought it in 1989, so I have no idea where they came from or why they're mismatched (maybe a tire shop screw up and there's someone else out there with the mirror set to mine). I haven't driven the car with the new tires, so I can't comment on anything related to driveability.
