You can do them with it in the car. I don't think the brand matters that much the gm rings are just really small and actually the dnj ones are really good I would just order the thickest vertical thickness ring possible that increases the rigidity of the rings and stops the oil burning from the thin rings. If you go and throw another brand in there and don't pay any attention to the size it will not do you any good u will just be rebuilding the motor the same way.... the design was bad not the rings. No brackets just the passenger side motor mount.. pull the oil pan off timing cover off cylinder head... only unbolt rod bolts, u need all new hardware, its all torque to yield. Im guessing the rings u do pull out of there will not look bad at all, mine had a broken piston. But yea the DNJ parts look and weigh the same and are made the same way and look the same as gm ones... your going to want new pistons. zzperformance.com is a good spot to get some hard to find parts like the rod bolts... U will want a micrometer to double check everything. These engines are actually a really interesting project maybe take some pictures for us all.
