mini tub suspention 1967 camaro shackle question

Im wanting to do a mini tub on my 67 camaro, I understand how the back of the leaf spring is moved using the offset shackles, but I don't understand how the front of the spring is positioned, with the front shackles mounts being outside the frame rail, are they move inward as well 2-2/12 inches or do they stay at thier current locations.. I was looking at these rear shackles good or bad??? http://www.jegs.com/i/Competition-En...oductId=743915.. just not sure how the front of the leaf spring is setup?

i dont know how wide of a tire i can go really with out narrowing the rear end.. like to go with a tire with 12inch tread width and 28 tall, i may have to go with a 10 inch tread width.. need to do some more research, i was thinking i had to narrow the rear end with a mini tub, but thats not the case i dont think after looking

The front spring mounts can stay, but the fuel tank will be in the way. Replace the fuel tank with a narrower tank or fuel cell and then slice your wheel wells and move them in towards the frame. The shocks also need to be relocated inboard of the frame. Then swap in an 8.5 rear end from a 2nd Gen camaro for an extra inch(narrower). Then get a good set of offset wheels and you can fit a set of 10.5x29 slicks in there.

Good Luck.

If you plan on moving the leafs inwards, the front spring mounts will also need to be moved (i.e. reconstructed) the same amount as the rears. For my Maverick, I made my own spring mounts based on the Mopar relocation kit that's for sale by most big speed shops. Just mini-tubbing alone might only get you an inch or so because the springs/shocks/bump stops will still be in the way.

thanks for the replies, I have a hardwood fuel cell replacing the stock fuel tank in the car now, so i know that will not poss an issue, right now as the car sits i have a 26x10.5 mickythompson sportsman pros that have a 8 tread width with a 2 inch drop to sit the rear the way i want it, I was looking at a 28 or 29 tire x 14 or 15 that has a wide tread pattern, the only thing about running a taller tire is that I've lowered it 2 inches with a 26, so running a taller tire would raise it up 2-3 inches so i would have to lower it back down another 2-3 inches to get the stants i want..At least for these tires, slicks are a different story tho, this car will be raced with some street use to. Have some decisions to make..

My Maverick went from a tight P275 rear tire to a P325DR with room for another 1 1/2" to the inside to spare. Here are some before and after pix with a shot of the new spring hangers I made from 3 1/2" square tubing. You can see the stock spring hangers and frame rails in the first pic. Second is the hanger boxes, third is the new spring hanger boxes installed under the cut out frame rail and the "pinch" I did on the rear frame rails for better tire clearance. These are before the tubs...
