yes you can backdate the FD. you also need the WUR because the earlier WUR had a vacuum fuel enrichment for acceleration. if you live where it is cold I would suggest a thermo time valve for added enrichment for cold starts.

I prefer the non lambda systems just for reliability.
unless your system is in need of repairs I personally would not spend the $$ just to backdate.

you can go open loop mode as suggested. you may have to tweak the control pressures.
