In my p-body I run a alum center 8-3/4.. its strong and light but when I built my Rampage I put a 9" in it.. the cost of the alum center unit now days isnt worth the price.. I went that direction to make the car light.. its a all moly 4-link with struts in the front.. I'm thinking about putting it back on the street but I have to buy another shadow so I can get a Vin from it.. I have the title but I tossed the dash when I built the car
