OK, what do you do when you notice the rear peg holes are just about the right size for a 7/16x14 tap, you have some angle iron from a old bed frame and a arc welder?
Yea I know it looks crude as hell, but it works, and I got about $4 in it!
Lower hole holds the bike upright on both wheels, roll the back wheel up on a 2x first and the middle hole fits, on 2 2x's the top hole fits. Pull out the 2x and it's pretty solid. A little wedge under the outside brace tightens it all up.
Feel free to copy this, just hope you are more practiced at welding than I am. Oh yea, YOU MUST ANNEAL BEDFRAME STEEL BEFORE YOU DRILL IT! I don't know what type of steel it is, or what's in it. But it will kill drill bits and hacksaw blades. Use cut-off wheels to cut it. I used 3'' pieces of 1/2'' water pipe for spacers and 7/16 x 4'' bolts from Ace Hardware.
