Where else can I put a oil pressure sending unit besides by the distributor? I want to keep my stock gauge working and I am putting a mechanical one on.

oil pressure sending unit????

by the oil filter. but one of those is supposed to shut the engine off when oil pressure drops too low, or something, i think.

Yes , by the oil filter . Carbed trucks have the choke circuit through it , and injected trucks have another circuit ( fuel or spark I forget which ) .
You can use it for a gauge , though I wouldn't use plastic tubing there .

You could also just buy a tee for the existing location, if it will fit. They make some odd shapes to fit in tight locations.
My experience with the oil filter location is that the hole might be bigger than 1/8 (what the port is near the distributor) and it might not even be drilled. On top of that, the way the block is shaped down there limits your installation of a sender, too many uneven surfaces. If putting a mechanical piece there to put a tube on, should be fine for that, if the exhaust isn't too close.

oem gms used a 45 degree fitting to offset the sending unit to clear the dist.

I "T"'d off the one by the oil filter. Not how how it happened, but I ended up with a big mess of fittings to get the T to work. Im not happy with it, but it works.

Definitely t it if you're TBI, just because I told you to and I can't back it up with any particular reason... trust me...

Thanks everyone. I will put a T on to run both.

since that's resolved, i have a related question.
mechanical oil pressure gauges are way cheaper than electronic sender units, but i don't love the idea of pumping hot oil into the cab. i've seen a hose come loose. it wasn't nearly enough to bleed the engine dry, but it sprayed made a huge mess and gave my friend minor burns all over his leg. suggestions for avoiding this?

Use stock gauges? 
Seriously, if you have a mechanical gauge you trust, put it up against a stock gauge, and see if they match. If they do, keep running the stock one. Personally, it really doesn't matter WHAT any gauge says, if it reads consistently, when the reading changes, you know there is a problem.
Other than age, and the fact that the faces aren't marked in small increments of pressure, there is no reason stock gauges are any worse than aftermarket. All operate the same way (when talking electrical).
I've got probably 15 stock gauges on my shelf that are between 15-20 years old, and all of them read the same as any other.
