Longer 1/4-20 nylon bolts for packing with DTR retainer

[etooey]

I've been using my DTR retainer with extra spacers and would like to add another. The longest 1/4-20 nylon screw that comes with it is just a bit too short for more than four spacers. Is there a good source for even longer nylon hardware in 1/4-20? McMaster maxes out at just 2".

Home Depot has some that are 3.5 inches and that’s what I use. I can post a pic of my stack later for you. I’ve been restoring full time with the DTR since 2007 and wear my packer everyday. I completely covered and retract but I’m going for full coverage erect. I’m about a third of the way there.
