Was sold an XLH, not an XLCH. Surprise!

Was trolling the interwebs last night and looked up my VIN. Apparently I was sold an 1975 Sportster XLH, not an XLCH. Sources around the web state that XLH's started with "3A" and the XLCH started with "4A." Anyway, after digging around some more, it doesn't seem like there's much of a difference besides the compression ratio. Still sorta bummed. Oh well, what can you do? To make myself feel better, I went and measured up the cable lengths I needed to order to run the new Z bars.

After removing the brake line, lookie what I found! I knew the master cyclinder needed to be cleaned, but I had no idea how bad it was.
