Did the pumpkin swap yesterday. Using the tech tip provided here helped alot. It went very well, did it in about 6 hours by myself, actual hands on time was probably 4 hrs, wife made a late breakfast about midway through, played with the grandkids a bit and went back at it. I made a jig for my floor jack to remove original and replace with the 4:10. All in all it went very well, noticeable difference on the road. Maybe I will be able to keep up with traffic now. Thanks to Stovebolt for the tech tip!
