Wouldn't need to get apart, as have at least one other N.O.S. muffler with upper heat exchangers. ;p

Okay, once again no one understands me... I am used to it, but still frustrating. Anyway, let me try again.

*N.O.S. muffler with N.O.S. upper heat exchangers still attached.

*However, the upper heat exchangers are loose.

*The nut did not turn either direction even with a 6' breaker bar.

*Instead of damaging the N.O.S. muffler, did as advised and left them loose.

*Was told the carbon build up and seal them. However, this was wrong and instead will do damage.

*Further, the copper rings are N.L.A. separate and good luck finding a muffler kit. Even the O.E.M.kit needed a good bit of exhaust paste.


Thank you so very much!
