[orange914]

i've always thought the 150 mph speedo was put in my 73 1.7 somewhere before me. i was looking at a link showing the correct guages. it said the 150mph came out in the 2.0 std. it was unclear weither the 1.7 with the appearance package had it. not avalible in 70 - 72. in 73 had silver button. in 74, no button and was know as black face.

how do i know if my car has apperance package? i've always expected it does. the console appears to be factory except the guage face is obviously modified and the other thing is the heater lever is straight non curved but the opening has bigger opening to fit the lever (factory looking not cut). all the others i've seen are a slot for the lever. it's from the first 1000 group pulled from europeon sales that came with oddities. could this be why? the car has been fairly unmolested over the years.
