Have a 71 Duster 340. What are some good wheel and tire size combos . How wide can I go in the rear without relocating the leaf springs? I was thinking 17s.

Below is a link to a thread that has all of the info that you’re asking for. There are 37 pages of posts. It takes a little bit to go through it all, but in my opinion, it’s one of the most enjoyable due to all the pics of great cars. I used this thread when determining what would fit my 73 Swinger. Ultimately, use the info from others for a baseline, but measure your car specifically before ordering due to unique features to each machine.
Post your wheel and tire combos.

Very good questions, a lot has been said on this topic. With 17s, you can go pretty wide in the front as they clear the control arms better than 15s.
Do you have the stock 8.75" rear? What are you running for ride height?
Do you have a 17" wheel style in mind? Offset/backspacing will be critical.
@72bluNblu is the guru on this subject. Searching for his posts would give you plenty of reading material.

Yes I have the 8 3/4. I put new espo leafs with a plus 1 inch. Open to wheel styles.
I hope Brian ( @72bluNblu ) doesn't mind me sharing this info which was saved directly from his advice. There are a lot of really smart, experienced folks on this forum. He's absolutely one of the most generous in sharing his time and advice.
"...you can get the 5 spoke legends in a 17x8 with a 5.25" backspace, which would work up front, and also a 17x8 with a 4.5" backspace, which should work out back. You could run 225/50/17's, 235/45/17's or 245/45/17's up front with the 255/45/17's out back. You could also opt for the 17x9's with a 5" backspace out back to squeeze the tire..."
He was referring to these wheels: https://www.summitracing.com/parts/vsw-141h7885gm0
Even if you don't like the style (I think they're darned good looking...) the sizes and backspace will give you a good head start.
Someone correct me but the rears should be the same between my Dart Sport and your Duster but a '70 Duster might have a tiny bit less clearance in the front than a '73+ Dart... so keep that in mind.
I'll also mention that this was mid-way through a conversation and this does not describe the absolute maximum amount of rubber that you can run.

Without tubing it the widest tire that will fit comfortably is a 275. All depends on offset
