I know the roads around Sevierville well!
Unfortunately I've only enjoyed them in our 88 Westy or rental cars when back there on trips! Would love to do them & "The Dragon" sometime in my 73 914 2L once restored!
Probably best to just live with your "DAPO dye job" & get it sorted out mechanically, then work on the rust issues (e.g.: my comment elsewhere on your front panel).
Given the relative rarity & ever decreasing numbers of "real" LE's, you're probably well served to eventually get it back to original eventually. I did a "rolling resto" on mine back in 80-84 before I went to grad school, so I wouldn't have problems, so it works well but required some planning being my only car & DD back then!
Mike Knox has made an excellent offer for the carpet set, so take him up on it. They're NLA now, so getting a nice used set & restoring it is the only alt. to finding NLA or new repro carpet. Get it clean (carefully) then you can have the worh edging redone with matching vinyl at a local carpet or upholstery shop.
Then you can work to collect the rest of the beige interior over time. You might want to look on TheSamba & eBay right now, since there are some bits available now - & then check back over time, but the 73-74 ones are the match, since pre & post MYs had different inserts & after even the smooth was different IIRC (72 may work with the basketweave, but the smooth is a match IIRC).
The COA may also confirm that it's a "real" LE under the options section, which will back up it's ultimate value & may lead you to do better/more original solutions in the process of all this rolling resto. If you join PCA, they get a $20 or so discount on COAs, plus 20% on parts from dealers from time to time, as well as 2 magazines per month & the events for your $42 annual dues. Although a counter-culture of that taildragging Porsche enclave myself since the 70's, I figured it was a good deal in my best interest to get my 914 resto'd.
Git er dun &
& then post us all some pix!!!!
