Speedometer swap

[car_cursed]

would I be able to swap a speedo from say a 75 Tii to my 74?

Mine is an auto and does not have a tach, but i do not know if that would affect this. thanks

Make sure the speedometer that you want to swap IN is the proper one for the differential that you're running. The W= xxxxx number stamped on the back of the speedo will tell you:

3.45:1 diff -- W=1.24 speedo

3.64:1 diff -- W=1.297 speedo (W=1.30 is close enough)

3.90:1 diff -- W=1.39 speedo ('76 49-State 2002)

3.91:1 diff -- W=1.393 speedo (E21 320is LSD)

4.10:1 diff -- W=1.4 speedo (1.461 calculated)

4.11:1 diff -- W=1.4 speedo (1.465 calculated)

4.38:1 diff -- W=1.559 speedo (calculated)
