Some early Sierra MK1 had a 3.92 rear non lsd 6.5” diff. I believe the crownwheel and pignon wheel were lighter than the 7” or 7.5” versions. Some 1.3 engined Sierra are supposed to have them
Problem is that seem to be an urban myth. I cannot find any info on that diff let alone find one for sale. Would be really gratefull for any information this forum can give me on this diff. Pointing me towards one would really make my year (sad life; sorry).
Quaife & Bara have heard from them but never seen one. Really hope somebody on here can help me.
rgrds,
