I am looking to reinstall the rear end unit in my 66 nova.The rebuilt 10bolt posi is almost done.So the next step, do I go with the stock mono setup or is there a complete multi leaf conversion package out there that bolts on for under 500.00 I have read that some modifications are needed if one wants to go with multi leaf.Is there any real benefit to a multi leaf?I would have reinstalled the original mono leaf back in the car but 1 of the eye ends broke on the original pair.I have searched the net and have a good idea on price but,just don't know what the best way to go is. The car has a small 283 built to about 300 hp, nothing crazY.3 speed trans and now a 373 posi. keeping it simple but yet complex! the rear unit is a GM 10 bolt 8.2. what is the best way mono or multi? any info waould be of help.
