cantilever wishbone help

I am gonna do a canti setup on a 06 ram. Question is... The bottom bars are gonna be 32 inches long. How long should the wish bone up top be? And how far apart should the points be spread out on the top of the rear end?

I'd try and have the wishbone as close to 32" as possible. Spread the mounting points of the wishbone as far apart as you can.

my onli other question is. IS a wishbone on the top strong enoufe to hold on a full size?

if installed properly yes

would a 22" Triangulated upper bars be better?

you dont want 22" uppers and 32" lowers. a wishbone is plenty, its been done over and over and over and been very reliable.

dam cuz the thing is i have a cross member at 22 inches but i was gonna run my lower bars from the stock leaf spring mount witch is 32 inches. So for me to run a 32 inch top bar give or take id have to cut the other cross member out
