You got a nice bike for the money. That was a great suggestion to try and get the old parts. I would get whatever you can from the friend of the seller so if you want to convert it back you can.

Kickstands on nicer bikes are add on accessories so yes this is normal. You can pick a cheap one up for $10 or less if you want one. I would give you one if you lived closer. Alot of my bikes don't have kickstands on them.

I'll look forward to more info and some pics.
