Sears red jack modification
Lifts good. Stable. No contact with the oil pan or other bottom parts besides the protectors on the frame. Put a couple of 1.5" tubes made from ABS sewer pipe between the forward lift ends and the bar between the wheels for stability when full up. Happy.

After spending a couple of bucks on the jack mod after that I think the whole thing was operational for less than $80. Before that I was trying to decide if I wanted to spend several hundred bucks on a lift table. That would be nice, but I think it can wait... that money can go into the mods I have planned for the next few months.
This topic is so large that the best info is buried.
I had to add washers between the arms and the pads to get it wide enough,, this set of photo's helps for jacking position;

Having the right side inner bolt right next to the kick stand was key for me,, but I still had too spread it out to get past the left side oil pan guard under the frame,, then lo and behold,, there's a clip on rubber stop to protect the frame from the kick stand in the up position that was in the way,, I just slid it forward.
Point is within this entire topic are about 12 way's to modify this jack,, the thread is so old folks say 5 1/2" bolts cost $8-10-12,, I didn't like the idea of using the threaded section of the bolt as part of the support,, I used 6 1/2" shoulder bolts with a bunch of flats, w/locks and nuts to get it right,
All that cost me near $30.
Get a light, shine it up under there,, crawl down on your hands an knees and look.
I've done the mod with 1/2" spacers, and it lifts my Fatty perfectly.
Now the question:
Has anyone found / used slightly smaller wheels on the front of the jack?
I'm a crummy 1/2" away from being able to use this jack, as is, on my old lady's lowered Sporty. The left pad is hitting the bottom rear of the frame just in front of the rear tire.
I've lowered the pads as much as humanly possible. I've put a little "bunk" on the forward side of the jack for the lock release bar with my grinder. That got me a whole inch. Now the bottom of the left pad is actually touching the front left wheel.
Now I know I can just run the bike up on a 1-by and problem solved, but I'm so close that my warped personality just won't let it go.......
Thanks in advance for the help. Several thousand minds are better than one.....
I read somewhere that spacing was not right on later model Street Bobs, without going through 65 pages does anyone know if the 1/2 spacer additions have worked with your 2014's?
thanks Vic for a great and easy mod!
EDIT: Never mind, found Squidhead's post and pics on page 53 or so. Figure the 2014 frame must be the same as 2013!

Bought the jack for $78 and when I first tried it, realized that it wasn't great on my Street Bob. While sitting in the shop where we work on our snowcats I googled "Jacking up a Dyna" and your youtube video was one of the first to pop up along with this thread on how to modify the same jack I had just bought.
Yesterday went to the store, got everything you mentioned (including the 1/2" spacers), total cost was $12. Back to my work's shop, to do the entire modification took less than 15 minutes (nice to have grinders and such available). Took it home, just jacked up the bike easy and stable. Was able to remove and re-adjust rear shock in 10 minutes.
Thanks so much man!
20.5" from outside to outside of the arms.

The only change to the original video I made was adding 1/2" spacers to all four bolts between pad and lift frame. Adds and inch of width and also helps to clear the jiffy stand spring. You don't change where you roll the jack under the bike. Use same contact points.
It's all good.

I'm really humbled by the responses to that video/idea. Who would've thought a simple thing would still be kept alive so many years later.
Thank you.
