TWM makes one which is 2" tall. I suspect it's the one Pegasus is selling for $246. There is a note that there is no provision for a choke assembly. Maybe it has to be cut off?
Something to this affect has been on my FUTURE todo list for a while. I had considered a radiused plate which sits on the top of the choke tower. I had also considered copying the TWM part by siameseing two standard air horns...this could also be the basis for a mold.
So Bob, you must have known that one of us would ask about your airhorn mods. Care to elaborate? pics?
BTW, Jam engineering is getting $62 for the snorkel.
