datsunaholic Posted December 15, 2010 Report Share Posted December 15, 2010 620s with 5-speeds had the same rear gears as ones with 4-speeds. Only Automatics varied in the same year. So, if you want something different, you need to specify which ratio. You have a '73, so it either had a 4.88 (common HD '73 ratio), a 4.38 gear (somewhat rare for '73 but common 74-78), or a 4.625 (Automatic Only). Link to comment
datzenmike Posted December 15, 2010 Report Share Posted December 15, 2010 Or 4.11 in the '79 manual transmission only. Link to comment
datsunaholic Posted December 15, 2010 Report Share Posted December 15, 2010 Right, but he has a '73 so it shouldn't (never say never though) have a 4.11 or a 3.9, 3.x anything. Link to comment
Radim Posted December 15, 2010 Author Report Share Posted December 15, 2010 It's a 73 with a Dogleg, i'm not sure what gearing i have back there i'll check when i have a chance but i'm pretty sure they didn't change it cause freeway speeds suffer, going 70mph at like 4-5krpm Edit: Just checked couldn't find the ratio without having to take off the diff cover, but my brother says it should be a 4.38 4Spd Link to comment
