Your first question is already answered. Your 2nd question: as long as the j pipe is into the opening in the muffler you should be good to go. The muffler flange normally doesn't fit all the way up to that flange on the j pipe anyway. Looks to me like you are ok on one side and maybe actually in to far on the other side. Your third question should be what goes in the top of the heat boxes on the muffler that the fresh air hoses fit into. There is a fitting that goes there also in addition to the collar on the bottom that you got referenced to in the bustorations link. Will find a link and send it. --- On Wed, 1/27/10, Gerald Livingston <gerald.tcb@xxxxxxxxxxxxx> wrote: From: Gerald Livingston <gerald.tcb@xxxxxxxxxxxxx> Subject: [tcb] muffler gaps??

What's supposed to close the gap between the muffler "heat elbow" and the heater box opening? I've never had a muffler with the "elbows". Always had paper/foil tubing all the way from the shroud to the heater boxes. 2. What might cause the fairly severe offset between the left and right j-tube slip fits? Right side is tight up against the heater box. Left side is 2" or 3" out. Do I need to wrap a strap around the mustache bar and try to pull that side in before I install the half-circle clamps? G2
