This is my elevator control horn from a 1998-1999 MKII tail. The distance from the center to the hole (pictured on top) is ~ 2-3/4” (Probably similar to yours in that it is slightly more)
The description tag identifies it as the “Elevator Control Horn” part number EL-055-02 for a “IV/320” Yeah, I didn’t expect that.

Greyhawk -- So I'm a "dim bulb", eh? ;-)
Angier -- Your elevator bracket is the older one of the two I mentioned. Although not as old as Scott ... err, I mean "Scott's" (Okay, Scott, we're even now.) You measured 3.75 inches from the pivot to the pushrod. The new ones have 2.75 (I measured 2.865 but 2-3/4 is close enough). I would recommend drilling a second hole 1 inch closer than the one you have now. There is no need to replace the bracket with a new one, and if the hole is already there, you can swap it easily after flight tests. Although I would start with the pushrod at the inner location.
I was unaware of the early aluminum brackets. This explains why the bracket kit I bought for $500 in 1994 had "extra parts".
