I was forwarded this link, and was surprised of the use of the Dzus bolts for the Spyder.
I have not seen that model of Dzus bolt before, the engagement section is much longer than the Dzus/Panex that I sell. That would effect the "feeling" of getting the Dzus bolts to fit.
It appears you purchased the shorter of the two Dzus bolts that I carry. The shorter have a Working Length of 12mm, but that is a misleading number. The Dzus clip uses 7mm of that working length, so you end up with a grip range of about 5mm. It would seem that the longer Dzus bolt for OEM Plastic, which have a Working Length of 14mm would be a better choice.
If you can photograph the Dzus bolt along side a metal Scale that is in mm, I can estimate the Working Length of these bolts. If not, I will make an effort to buy a single bolt and check it myself. I like to be able to tell people what fits and what does not fit for special applications. If their is anyway I can help out, please let me know.
I am now working on specialized replacement Dzus kits. So if exchanging the Dzus bolts for your Spyder is something the community needs, I will try to develop a kit for you. If anyone is in the Phoenix, AZ area, I would love to check out their Spyder for this kind of kit.
