Back when In 92 , My Friend Chuck’s, 74 400 RR eat it’s 727, him not being a car guy and broke musician couldn’t afford to send the car out to get it fixed, I convinced I Could rebuild it and put it in over the weekend if I had the parts….well got the 727 out rebuilt it, put it back in , filled it up with fluid, put it in Drive…nothing just engine noise and no movement, put it Reverse nothing, I’m panicked , we pull the box back out, tear it down, Call my dad, then call my uncle, go over this trans one more time…put it back in, re fill it…nothing, no forward no reverse….I’m stressing out about to cry , Chuck has to get to work in the morning, it’s 2 am on Sunday night….I put my hand on the drive shaft leaning against the wall……yeap that’s right the DRIVE SHAFT leaning against the wall….forgot to install it twice…..every now and then out of the blue Chuck will ask me if I’ve seen the driveshaft lately
