(Online photo, not mine) My car has been on the hoist for 4 days now ! The problem is the rear flex line where it mounts and passes through the frame crossmember.

CP'ers For reference, perhaps someone can use this someday. For anyone who has converted their 65-70 B Body from front Drum to Disc, or even to Disc Disc, you know that unless buying a complete system or kit, finding the correct tube nut sizes takes a little research.

We started to talk about this on another post (my 69 2+2) You guys gave us some really good points and ideas of what to check. A great rainy day project that I tackled today. I ran new ground straps to the tank and the cluster. Tested to make sure each were showing good ground. No luck with the gauge. Got out m...

Yesterday I installed the Pittman arm on my manufactured Saginaw box. I used red locktite on the new nut along with the lockwasher. Used my big electric impact gun to run the arm up onto the splines. Gave it a good hit. Now it appears the box has some very slight play off center. It had zero play previous...
