Questions about the "Shebly Drop"

Questions about the "Shelby Drop"

I am currently embarking on a disc brake conversion on my 68, and I ran across the shelby drop in my search for resources. A couple of questions for anyone who has done this:

Does it create any structural issues (extra holes where they shouldn't be)?

Can any shop still perform the alignment? Should I tell them it has been modified?

If you have any other general thoughts on making these kind of mods to a car you are trying to keep as original, yet driveable as possible they are welcome. I have always thought if I made massive changes to the car I wanted them reversible, just in case I did ever have to sell it. (I am also thinking about storing the old drums/spindles somewhere when I am done - am I paranoid?)

Thanks!

Yeah I saw the reusing of the drum spindles thing for the first time today. I bought a full granada front end for less than 200 a couple of months ago, and I finally got started on it a week ago. I'll look into it though.
