MA - 40 ....Stands for MethAmphetamine 4x.. I am sure alot of that was involved in this old gravel pit racer before I got it . Here is day one of this project. The more I cut out the worse it gets!!~ Last pic is of the rear end thats going back in it.. If your into tradition stop following this post now. If not follow and watch me waste alot of money building a bad ass 4x dragster. Before you ask. Too far gone to restore to OEM..
