Two current issues. Oil Leak and tank valve

[MadMAX77]

I have my '85 K20 worked back up to running. I've done a TON of stuff with it. Right now, I'm losing oil because my dipstick tube broke right at the bracket. I also can't get to the fuel tank selector valve itself. The dipstick is on the RIGHT and it runs between my headers cylinder 6-8 down into the pan. All the available replacements are really short and won't work. I cannot locate a replacement part anywhere around here. Any suggestions would be appreciated!

Any tips on how to access and remove the fuel tank selector valve would be greatly appreciated.

I'm new to the forum and hope I don't commit any social errors. Thanks for the help, in advance.
