Just a couple o things to add. Looks to me like it's a '77 M-model by the newer style flap switch and it should have dual landing lights in the nosebowl, based on the 2 switches in the panel,

a plus.
External plug for ground/battery jump starts, a plus.
Incorrect older style wheel pants from a late 60's model.
I'll swap ya a standard airspeed indicator for the TAS indicator...

New center console. (110.00)
VG's... 800.00 installed
Skybolt cowl fastener kit, 400.00 plus 10-12 hr. installation.
Rebuild gyro, about 240.00, 700.00-1200.00 new
