my metric s/ps is built like a mod from the front stub back to the rear control arm mounts behind the rear cross member it is 2x3 tube. i wanna make it underslung like on your mods i believe it is what you 'all call a birdcage. couple of ?s. is it worth it we have one other car here built like this? how much clearance isa neede under the rearend between the housing and the bars? pictures of an older imca with a full frame and 4 link would be helpful.thanx

the birdcage is a floating device on the rearend, it allows you to put on a free floating 4 link, i mean pinoin angle is independent of the 4 link bars, that is what the pullbar is for.
as far as underslung, adds some strength. i would go about level on rr and make it so the lr drops down where the rearend will come in contact with it, alot of cars are dropped like 2 inches to 3. that means when you jack it up and the rearend hits the underslung, the lr can travel further than the rr.
are you wanting to make the 4 link like a mods? they are floating ones, have a ton more bite than a stock 4 link will.

just looking for added strength in the rear, i have to add weight in the rear anyways so i fig i would make it functional in two ways weight+strength. i would love to got to a full floating setup but the way our rules are going it'll be a few years before we can do that. basically i'm trying to stay a step ahead of everybody in what we are building. when i ran 4cyl super stocks everytime we came out with a new idea 4 other cars either showed up[ with it or found something to outdate it. with the "pure stock" class i'm in now since i started i've been trying to stay a step ahead. so far i've been doin good i had the only mod style chassis car till the end of this season when our track champ went out and had a professional build one almost identical.thanx for the help on the measurements i was not sure how much travel room to leave between the rearend and the bars underneath.i wanna find out about the legality of running the 3 link gn style rear we asked last year and got brushed off we have a tech meeting soon and we are going to ask again.
