Probably but the existing holes are 10-32, not 1/4-28 as required for the 
horn mount and for securing the wheel

Might work. Holes do line up in three positions (are triangular).

Depends on whether you want the turn signal canceller (snaps into the back 
of the hub) to work properly. Part of the concern is so that all of the 
other pieces included in a steering wheel adapter kit will would properly 
to minimise other fabrication.  Since the three holes must be drilled out 
and tapped anyway, it is almost as easy to put them in the right place. 
Could then make them through holes and tap all of the way.

Obviously since the wheel turns full circle, it does not matter where the 
horn pass-through is located but then an additional hole will be needed 
either in the wheel (and any subsequent wheel) or the hub. I just think it 
easier overall to keep the factory orientation and add the three new 1/4-28 
holes.

Am going to need another adapter anyway since the target wheel has no 
center and is made to utilize some long-lost column. Has anyone ever seen a 
wheel like this (picked up at a swap meet years ago) ? 14.75" Diameter and 
no discernable markings. Note the odd seven screw mount. Is similar to the 
prototype-never-seen-in-production wheel shown in early advertisements of 
the 69 Firebird Trans Am. The production "Formula" wheel which appeared in 
1970 has six screws, no dish (this wheel has about a 1" dish), and a 2 3/4" 
center hole (this one measures 2 1/4" and is probably for a non-keylock 
column). Adapter I am working on is in the center.
