My truck never had a front sway bar. Pulled into the shop earlier this week to try installing new sway bar from Classic industries. Not the right bar. 10" too wide? must have been for a 4WD. Not sure. Wrong brackets. Put it back in the box and returned it. Listing was for a 2wd. While at that, I tried fixing my tranny leak. Now, since I fixed the shifter rod seals, it was leaking worse. Got under there and found it leaking badly out speedo cable port. Replaced the entire cable/gear assembly. Found the top inner seal was shot. Replaced and looks like the leak is now gone. The white seal shown in center photo was shot. Replaced old with new shown $12 from Summit.
While underneath, changed oil from 10/40 to 5/30 for winter (Penn grade semi synthetic with ZINC).
Also, removed carburetor for adjustment (the Rochester VAriJet 2 on the 250-6) has a non reachable idle/mid range mixture adjustment screw. I made a special tool for the screw, and adjusted the screw in (I was too rich), replaced the carb with a choke adjustment also, and got everything back together. The adjusting screw is inside that tube under the nearest vacuum hose. Only 2" to valve cover. The screw is about ½"down that tube. It was originally totally hidden and you have to cut the carb to get at it.
I think the truck is running great with no leaks from tranny. Parked the truck in (my wife's) driveway to check for leaks. Wish me luck.. No, I think I got it this time.
