Here are some pics of four windshields I've put on a VN750. The red one is a 1994 one just like yours, but for windshield purposes any VN700/750 1985-2006 will mount and look pretty much the same.
1 - A VN750 with a National Cycle Deflector DX screen, which mounts to the handlebars:
Which is low profile and sporty, but does crowd the instrument cluster:
2 - I also tried the larger National Cycle Street Shield EX, but I didn't like the mounting system:
Like the Deflector shield, it mounts without having to move the turn signals, but because it's bigger than the Deflector, it needs both handlebar AND lower mounting points that are ball-and-socket arms looped to the forks and affixed to the windshield with glue. Which came off after a month or so of riding. I sent the shield back, got a replacement shield and it happened again.
At that point I said to heck with it, if I'm going for a shield larger than the Deflector I'm going to bite the bullet and get a Memphis Shades one and just move the turn signals.
3 - Here's the Memphis Slim 17" windshield (I think the "Fats" is too fat):
Yes, you'll need to relocate the turn signals, but really it's pretty easy. I was pretty much a total newbie at this sort of thing and I did it in less than 2 hours. I did need to shim the clamps though, they were too loose -- I ended up using some electrical tape wound around the forks to thicken them up a bit.
4 - Maybe it's because I was used to the Deflector shield but I found the 17" windshield too high. I exchanged it for the 15" height, which I like a lot:
I like how mounting the windshield off the front instead of the bars gives a nicer view of the instrument cluster, especially when I tried adding a GPS:
