scottser,
I tried searching here for an earlier "Coliseum" post where I talked about the simple modifications you are inquiring about... but I couldn't find it, so here I go...
I have a Ludwig L483 that I ordered with the P-87/P-34 combination. I really love the throw but hated the butt after I got it. The individually adjustable snares sounded like a good idea at first, but become a PITA, especially if you wanted to experiment with different snares.
To get around this issue, I just removed the P-34 an added a new P-32. I re-used all three mounting screws - two for the P-32 and one to fill the remaining P-34 pre-drilled hole. I also currently use snare cord for this butt although I know I have used tape (plastic strip) at one time or another.

I used tape (plastic strip) on P-87 throw end, and re-used the P-87 snare hardware. The simple mod was to put a hole in the tape and bolt it back together.

The newer P-33 looks better than the P-37 I used, but I'm not sure of the fitment... as an option these go new for under $20. I think you may have to mount this one "upside down" as I have heard of issue with the head touching the butt. Mounting upside down buys a bit of real estate.
If you just gotta' have a P-34, you can find for a good price like this $10 offering:
