The saga continues of the fix-up of the 1967 250 S utilizing parts from the 1968 280 S parts car. The 250 S is now drivable. I have work to do on the carbs (webers), exhaust, lots of other things.

Prior to this weekend, the 250 S had the rediculous sag and wonky camber in the back end that is associated with a bad hydropneumatic compensator. The 280 S had the spring compensator, and we switched them so now the spring is in the 250 S and the ride, camber, etc is really quite excellent.

The strange part is that the hydropneumatic compensator appears to be very recent. The rubber bits have wax on them still and after I cleaned off the grease the thing looks new. But when I push/pull the plunger it just moves with no resistence.

Is there something clever I can do with this that won't cost me $$$? Although the ride is nice with the spring, I suspect it is nicer with the hydropneumatic compensator...

thanks
Scott

Allegedly the compensator does not affect ride, only ride height with a load in the rear. These can apparently be rebuilt by a proficient shop. I don't know who does it, maybe someone here knows.

Yup. I had a boge hydropneumatic leveler in another vehicle. Slightly different application than a split-axle, but it worked the same way. Twenty-odd-years ago, I think I had info on someone who worked on them, but I would have to do some real searching to dig it up.

Look up Nivomat.

This site has a diagram: Self-leveling suspension

My Charger has Nivomats on the rear (not stock, part of the SRT suspension swap I did). Even with 4 passengers and tons of stuff (over 600lbs between the back seat and trunk) it never sags. My 108 was the same way, even though the rear sagged after sitting, going over a few bumps popped it back up in short order (going down the driveway in Bear Creek was enough to do it). I had over 300lbs of tools & parts in the trunk at one time and never realized how much it actually was because it never rode low. I noticed the difference in how it didn't sag nearly as much after sitting only after I removed the stuff.
