I have an older red Craftsman jack but it doesn't work on a Dyna without a frame adapter of some type. I never lifted a Dyna with it because of that. The J&S jack is far superior to the Craftsman and I lift my wife's Dyna with it. No adapter needed.
I have a J&S and it seems like I still should have the frame adapters for my 2008 Super Glide Custom. Where are you placing the arms to clear everything?
That shark fin that sticks out below everything, There to protect the oil pan. Towards the rear on the right side. The other 3 points of contact are frame rails.
On the FXR, the kickstand bracket on the bottom catches first and makes it wobbly on the jack. A 1/4X1X6 piece of aluminum on the opposite side of the jack stabilized it.
That's a whole 95¢ off the Harley Davidson retail price, but they do appear to be NIB condition.
Here's what a used (20 years) set looks like. Also mounted and ready to be lifted. The little hard plastic channel is the piece that goes under the shark fin. I can't count the times I've had to replace the double sided tape that holds the plastic and rubber pieces together.
Notice any difference between the cheesy stamped steel fin from the later bike and the Manly forging from the older bike.
How do you like my mud flap drip tray? I find them all the time down in the shopping center parking lot. Can't argue with the price.
I did same to mine ( as FWDWG03 did to his ) 1/2 bolts, reamed holes also.
The only difference is I cut cross bar and then beat a 12” x 3/8 “ pipe inside.
However with cross member pipe still in place it will only lower to 6”, enough for me … but if not enough you could re-weld back farther.
Widened by 6”… now a little over 12 1/2” between platforms.
I have an older Dyna , so no issues with the fin, but it is definitely easier to miss jiffy stand & drain plug & sump. Seem to have good stability.
