We have air shocks on the back of the 68 Firebird for tire clearance reasons. The set we have is leaking. Problem is, we can't seem to find any air shocks that will fit the multi-leaf rear suspension on the 68 Firebird. We can find ones that fit a 68 Camaro or 67 Firebird, but nothing for the 68.
Does anyone have any idea who makes air shocks for the 68 Firebird with multi-leaf rear suspension?

Thanks.
I have these that I took off my 68 Firebird.

I just did a Google search. One guy said that the only difference in the mono & multi-leaf shocks is the size of the hole in the bottom eye. He said that he removed the metal bushing, lubed the rubber portion of the bushing, and it slipped right on the bolt.
I suppose you could just change out the bolt, to the smaller one.
I always just raised the body with adjustable rear shackles. But, some don't like the way that looks.
Consider re-arching the rear springs for additional clearance….Air shock ride terrible, will increase your vehicle bottoming out on the front springs, and fail often.I ran 2 sets, on differing cars. They always slowly leaked down, another maintaince issue to watch.
New springs cost close to the same as air shocks and solve a lot of issues. The car wasn't made to be held up by the shocks.
I agree, a portion of the weight of your car is riding on the upper shock mounting point, not the springs. But I do have them on mine, have had new springs in the Bird house for a year and have not had the chance to replace the sagging ones yet. The Air shocks keep the car up at the wanted height, but the ride sucks and every time I hit an off level bridge abutment it feels like somethings going to come apart back there. The fitment issue isn't just with the size of the stud or bolt that attaches the lower shock eye but the length of travel. The 67 and 68 lower spring plate/shock mounts are different heights, one requires a longer shock than the other.
I installed new multi leaf spring with a 2" "higher" arch than stock. I still needed air shocks to get The height where I want it. Also, I fill them separately to level out my rear end. Ride is fine. I run about 60-75 psi, depending on which side.
