Tach-A-Matic Location On Various Chassies

[tarcoleo 119]

There is a 2 inch difference in location on the chassis of the

TAM device between my C-111 and C-81. The C-111 location

is further aft than in the C-81. Is there a standard location for

the TAM, measured from where to where?

(Hope this is not a double post.)
