This was maybe 3 seasons. Outfront John sells a set of 8 seals that pop in there. I put a little grease in there and it appears it should work just like a wheel bearing seal. With much less movement. I believe they will last MUCH longer without getting exposed. Edited May 9, 2021 by onanysunday Quote Link to comment Share on other sites More sharing options...

This pic shows the bottom plate you weld in. This pic also shows a partial view of a second side plate that gets added.

Also at that time I added the circled triangular gusset. Both my arms were cracked at the tube from hard use. Quote Link to comment Share on other sites More sharing options...

IIRC it was a 9/16 super high strength bolt. This job is tough for two reasons. Number one the stock perch is very hard material and hard to drill or get a reamer through. Access is hard to get in there with a drill. Number two it is hard to get in there to weld those tabs in. But doable. Beefy! Also notice I took some 1/8 plate, wrapped and welded to the tube where the uniball presses in. I have heard of at least on failure there and did not want to take any chances. On those tabs I did machine thick spacers to move each gusset away from the tab slightly. Needed for clearance and to get it welded in.

Ask me how I know. This was a lot of work and destroyed an airbag and a trip. Quote Link to comment Share on other sites More sharing options...

This was my fix and I put 840 miles on the car in March and April alone. So far bulletproof. In the old thread that got lost John had posted up some ideas for an easy fix and my guess is even a kit he could sell. Chizzle had mentioned maybe putting in two uniballs in place of the factory bushing and sleeve. Great idea and IIRC I had looked at some uniball/spherical bearing sizes on RKs website. It looked like there was a size of uniball that would go right in with maybe a 1.3" long spacer in between the uniballs. My set up gives tremendous support and was simple to do. Very simple design with cut off bolts, some small pieces of tubing welded on, and rod ends. I kept the factory bushing in the middle. Notice my rod ends were larger than the ones shown above. I wanted a lot of surface area. Edited May 9, 2021 by onanysunday Quote Link to comment Share on other sites More sharing options...

If you have an older Gen 4 the airbag perches may not have this gusset. I had welded this gusset on mine early on and did not even know Funco had upgraded it. I had to replace one side when I broke the lower bolt and to this day I have one of theirs and one of mine. lol Quote Link to comment Share on other sites More sharing options...

Found this in my pics. Airbag that got bent real bad. Made a fixture and welded on bolts to pull it back somewhat straight. I bought a new one but this bag is sitting in my moho as a spare. ha Edited May 9, 2021 by onanysunday Quote Link to comment Share on other sites More sharing options...

Don't use very much grease. At first when I put it together pushing in the spacers hydrolocked and wanted to push the seals back out. I had to much grease in there. If I did it again I would be very careful and keep the seal surface dry. Use a tooth pick to put grease around the uniball and move it around to work the grease in. I just used CV grease. 1 Quote Link to comment Share on other sites More sharing options...

Is that -10 or -8 line running from the tank to the filter and from the filter to the pump? If it’s -10 did you have to open up the outlet from the tank?

I added a 3/8 pipe here. Thinking I was running the car with a fitting for a -10 that screwed into the 1/4 pipe hole. You would have to look at the ID of the fitting and your line. My HP level for this car has always been 450-485. 58 psi with the A1000 pump. Ton of hours on that pump and I have a new spare sitting in the moho.

I’m less than 400 with a stock Northstar. Going to put that pump in and would rather not pull the tank to have bigger bung welded in. Did you run the 1/4 pipe to -10 with that pump for a decent amount of time with no issues? Quote Link to comment Share on other sites More sharing options...

Probably because we were in their welding on it. I am pretty sure I had a dash 10 suction all along on the stock bung. 1 Quote Link to comment Share on other sites More sharing options...
