you need an 1152 speedo for 165/15-(approx 75 aspect ratio originally) with
a 3.7 rear.
     The old 165/75-15 tires are about  an exact match for new 185/70-15
(diameter-wise)

1184 for the 6.95/15 tires and the 3.7 rear

1280 for 165/15 and the 4.11 rear

1315 for the 6.95/15 and the 4.11 rear

I know I left it a little hazy.  These are the definitive answers to the
best of my knowlege.
