I like the leaf springs for a non prostreet car or daily driver, I had stock 1936 leaf springs on my humpback and drove that truck for over 130,000 mi. in 12 years amd my wifes sedan was pro street and I used the stock leaf springs that were on the 80 datsun frame that I used. that car also had about 12 years on it and over 120,000 mi.
she even drove out here when we moved to CA in 1993

I am running a triangulated 4 bar on my roadster PU and ladderbars on my racetruck, the roadster PU will have air bags and the racetruck will have coilovers.

for a cheap reliable rear setup, good old leaf spring work very good but I like to upgrade to a newer mini truck springs instead of 70 year old stock springs.

but 4 bar or ladderbars work good as well but you have the added cost of air bags or coilovers.


and Dave your frame has a X frame in it and you will not need to do any boxing Ron....
