Posted January 1Jan 1 comment_672753 Regarding the deep (full-size) spare tire tubs, I have seen two differences. 1) Some have one drain hole (fwd) and some have 2 (fwd and aft). 2) Some have what looks like a heat shielded welded to the side next to muffler. The question: what is the date of these changes? Before I weld in my salvaged tire tub I wanna make sure I have the correct one.

So sometime between 5/71 and 7/76 they added a second drain hole. Also, my 5/71 tub did NOT have a heat-shield on the side. Here's a pic of a later tub that has the second (rear) drain hole and a heat shield. I wonder when this change was made.
