As above just looking who knows. Trying to find a stronger option for my 1988 mirage cyborg 4wd got 3.545 ratio in it atm. Had heard that some late modal starion 3.545 crown & pinion wheels fit a l300 van/sigma 10 bolt diff head. Or could i go this a ex lancer gsr 10bolt diff (trying to find one is another story) and if theres any lsd optionns i can go with can someone shed some light thanks Gary.

aww ok so the diff heads are a different size dam haha ruffly whats the width of the whole diff head and axles

ok im new to this site im trying to find out some info on diffs first question is what do the 3.909 ratio solid rear diffs come out of and if the internals fit in a libero diff head im building a 1988 cyborg and want to put the 3.909 ratio in help would be appreciated.
