Steering wheel interchange 1970's

[TJ Hopland]

Are other GM makes of steering wheels interchangeable with the Cad's as long as they are T&T?    My first concern is will they fit and bolt on.   Next question is it possible that the centers will change?  I see some of them have a similar spoke layout?

[TJ Hopland]

I am starting to think they may be the same.   I notice that the T&T option for the other makes appears to match the Cadillac spoke layout for the year even if the regular wheel did not.

Anyone know if the wheel itself is the same T&T vs regular?

[TJ Hopland]

Would a part like this show up in an interchange book?  Anyone have one?    Would the book also say if in theory the colors were the same between the brands?

I know that '70s Buick Electras used the same wheels as previous Caddy's, like '75's offered a '73 Caddy wheel and '78's offered a '76 Caddy wheel.
