Mopar Mikey Posted December 11, 2015 Report Share Posted December 11, 2015 As most Datsun nuts probably already know... You can swap spindles and kingpins from a1973 probably.. To a 1977 621...ect..truck..and bolt them into a 1972 pl521 For me this was a new venture I have mostly Mopar and gm vehicles But recently I came across my wicked awesome pl521,The kingpins Were so..hammered out of it...typical no maintenance ! Anyhow My buddy from his work had a 1973 duel axel621 truck Everything was a bolt in swap ....except you have to use 621 Bearings' drums ECT...leaving me with the axel studs a different Diameter and thread size...love the crap out of her though! I sure like this sight Im just a little computerly chalanged Maintain you're vintage eh! 1 Quote Link to comment
