Bolt in 4-link or mono leaf springs

Probably will be a Dana rear end. I just retired about a month and a half ago and I should’ve had this car finished already but it’s been setbacks after setbacks. I’m planning on being a serious racer for a few years then playing around at test and tunes. I’m planning on racing the March Meets and hot rod reunion every year until I grow tired of it or can’t afford it anymore. LOL!!!
I'm sure everyone knows set backs lol.
I was flying on my build, I got the cage certified and now it's about to expire March 2027
Dammit !
