Well, we have belt.
The 90"
would have worked perfectly, but I totally forgot about the larger alternator pulley on this car.
When I replaced the alternator a year or two ago, it had a larger pulley on it than the original.
The stock belt went back on, but very tight.
If the belt hadn't been worn in and stretched, it might not have fit at all.
I said what the heck, and left the larger pulley, but I forgot all about it until I tried to get the 90" belt on.
So, I went back and got a 91". The 90.5" might have worked, but I went straight to the sure thing, and it works great.
Thanks for all the input!
