Based on the pics, I'd say the bike is mid-80's. I assume it has horizontal rear dropouts. Dropout spacing is probably 126mm. Should be easy to convert to fixed. Can't tell what crankset it has, but may be useable. The main thing is to acquire some wheels. It would be easier to purchase a rear wheel already set up for a fixed cog than try to re-dish the one you have. There are a lot on ebay to choose from. You have two choices for drivetrain parts (chain ring, chain, and cog): 3/32" or 1/8" width. 3/32 is basic road bike width, 1/8" is track. I have two fixed gear bikes, both with 1/8" (parts cost about the same, but are a little stronger and take longer to wear out). If the rear wheel comes with 120mm spacing, you may need to add spacers to make it fit your frame without putting stress on the rear triangle. This is VERY easy to do, and some wheel sellers will offer to include spacers if you put it in the notes. If you can use the crankset you already have (which is 3/32), remember that you can put a 1/8" chain on a 3/32" chainring, but not the other way around. SRAM PC-7x chain is 1/8" and comes with 3-piece master link. There are lots of others to choose from, but that's what I use. Another thing: keep at least one of your brakes, and if you buy new wheels, make sure you get some that have a braking surface (track wheels do NOT). It's a lot of info, but it's not all that complicated. I am sure there are people in your area who can help you. If there is a bike shop nearby, they can give you advice on what to do and how to do it. YouTube is a great resource, also. Good luck. Have fun. Stay safe.
