I believe you have a freewheel.

Looks like a freewheel to me too. I just went to the Nashbar website and the conversion kit is for a 7/8/9-spd shimano freehub/cassette. I've done both types of conversions: freewheel and freehub. I used Performance's conversion kit which is essentially the same with different cogs.

With the freewheel approach you remove your freewheel (using appropriate tools) and replace with a BMX-style ss freewheel. Then respace the axle to get a good chainline. For me the inner chainring always seems to work the best. Then redish the rear wheel to center it in the frame. Sometimes this is unnecessary, if you get lucky. I did. So did my neighbor.

Looks like a Normandy-made "Schwinn Approved" freewheel. The OP will need to find a shop with tools appropriate to this vintage (60s-70s) bike. It uses this remover:

Well I went ahead and ordered what I had thought would be the right tool. I ordered the Park Tool FR-4 Freewheel Remover (FR-4), but it is way to small to fit. Is this the right tool?

This is just a guess, but perhaps you need to remove the axle to get the tool in there? I think I have seen some that required that.

No, the Park tool won't work (as you discovered). The VAR tool I referenced earlier is still out of stock, but United has come up with a replacement:



Not cheap, but those freewheels are becoming pretty scarce so there's not a big market for the removers. Maybe your LBS has the tool already?

N.B. You may have to remove the locknut and some spacers to get the tool to engage.

you know, you can just use a 7/8sp chain and cut it to the gearing you want to achieve your single speed.
