datzenmike Posted June 13, 2011 Report Share Posted June 13, 2011 Find a '74 620 with an automatic L18 in it. It came with the 4.625 H-190 axle. Link to comment
Dime Dave Posted June 14, 2011 Report Share Posted June 14, 2011 From my notes 620 long beds were 4.62 ratio as well. 4.88 are eadily available in 520 & 521 with the 1.3L. A 320 center (4.88) can be used if you swap out the side gears to the later truck spline. Link to comment
Jersey Posted June 15, 2011 Report Share Posted June 15, 2011 The '73 620 with an L16 and an automatic also has the 4.625 gear ratio. The applied model is: PL620KTU. Link to comment

The '73 620 with an L16 and an automatic also has the 4.625 gear ratio. The applied model is: PL620KTU. I think you're right. Forgot about the early L16 autos. Link to comment
