Kraig,
I agree but disagree, it depends on what you use as a reference point. I agree that what Shultize has has the correct fittings from the block to the muffler, but it depends on your reference as to whether they are in the correct order. The order according to a TC-82 Parts Catalog for the Original, dated 2-61, (with Revision 6 dated 2-64,)list item 81 NUT, lock P/N 138 909 R1, item 82 ELBOW, street P/N 385 309 R1, Item 83, NIPPLE,
elbow to muffler P/N 127878, and item 84, Muffler, exhaust P/N 385 307 R1.
However, looking at an Operators Manual for the Original, dated 12-15-61, the pictures in the manual (Illust 22 on page 22) show the nipple screwed into the block and the elbow screwed onto the nipple, like the picture Shultzie posted. Keep in mind that the pictures in this manual are of one of the 10 Louisville prototypes by evidence of the smooth foot rest rather than the perforated foot rest, and we know that at least one of the prototypes was used for the purpose of compiling the Operators and Services manuals.
So, this
would think as long as it consist of a close nipple, street ell, and lock nut, in either position, it would be correct, but I believe the production run had the elbow in the block and the nipple between the elbow and the muffler. I say do it the way you want it and I'll get down off this soap box now.
