Suntour Derailleur and Grip Shift
I am in the process of converting a Free Spirit 10-speed road bike into a 5-speed commuter bike. I took off the large chain ring and front derailleur, and replaced the rear derailleur with a vintage Suntour VGT Luxe. I wanted to use a 5-speed SRAM grip shifter, but had read that it probably would not work with said Suntour. Alas, it worked just fine, hitting all 5 gears perfectly! To quote the famous Honda car commercial, "Isn't it great when things just... work?"

What separates the V-GT Luxe from a lot of derailleurs of that period is the barrel adjuster.
You got lucky.
Sort of like when I used 6 speed Dura Ace shifters on Suntour XC Comp derailleurs on a Suntour Perfect 5 speed freewheel.

I used to run 6sp 105 shifters, XC Pro derailleur, various freewheels from sedis and shimano. Worked great.
The thing to avoid is SRAM MTB derailleurs, they need specific sram shifters, which dont come in 5sp anyway.

Bikes are okay, I guess.

What he said. Nice that it worked but you could never predict that, or necessarily expect it to repeat. The V-GT derailleur predates indexing so anything could have happened. When the Grip Shift stuff first came out you could get those that were Shimano-specific and those that were SunTour-specific but compatibility with that derailleur would have been a crapshoot even with those.

You never know until you try 
I didn't even know SRAM Grip Shifts came in a 5-speed model.I thought they were all 7- and up.

My friend did something similar. His daughter trashed the Shimano derailleur on her bike, with had a 7-speed indexed shifter, so I gave him the original VGT from my 1971 American Eagle Semi-Pro to try, and it worked great, except for the daughter complaining about how "old" it was. Kids these days!

Here is the finished project ...
Everything works and it rides very smoothly. The rear brakes were hitting the tire when fully extended, so I had to add a bracket to lower them about an inch. Should make a good "town" bike for someone.
