Re: 1991 Zuk and front lockers....!
Gee, I wish somebody would have told me I can't install a lockright in the front of mine because it has a one pin carrier (88.5 Samurai) - BEFORE I DID IT.
Whoever started that crap is wrong.
I've been running a Lock Rite in the front of mine for over 2-years, Wheeling it hard (ask Zukiman how hard) and I haven't broken anything.
A four pin carrier is prefered but not necessary.
Your blow-field will break before the carrier.
Zook94 described the differences in the carrier, but the lock right still works.
Ask around to see if anyone has broken the one pin carrier.
I doubt you'll find many at all (if any). I want to see pics.
