<p dir="ltr">Thanks for all of that info. Now I am looking forward to the hunt for part numbers and model stamps. It is like a treasure hunt. </p>
<p dir="ltr">Here's to finding a 3.67 or 3.71 gear ratio. </p>
<p dir="ltr">If it is 3.91, I might just install it as is to see what it's like. I was getting 26 on the highway before. If I don't suffer much there or with top speed, I might just leave it the way it is. I don't mind experimenting a bit. </p>
<p dir="ltr">I will let everyone know what I find as soon as I find it. If it ships Thursday I should see it middle to late next week. </p>
