No Hassle A-body Headers..... It was done, unbelievable!

I'm just learning about these. I'm used to pulling the motor up about 4", removing steering linkage, kick down linkage, shift linkage, just to get the drivers side in. i had my exhaust pipe off because i'm installing the dynomax turbos, so i thought I'd see how (or if) they'd fit. Honestly I removed the manifold, 2 starter bolts and slid that back and had the headers up in there all in about 10 minutes.
The very first time I put that right side driver side header in my 72 Duster years ago that was it! I had the car jacked so high I believe the back bumper was touching! I had to steering box loosen the motor jacked up everything I could take off taking off with my brother-in-law pulling with all his might and me having it up on in underneath pushing and banging it! Never again! Always pull the motor! And put it in before doing anything else and then put the motor in.
