well, I am getting the 4bolt jig for the dle anyway. If fitted with a spring washer under the head, the bolts will never come off
With regards to the spinner bolt, TT told me that they supply a 10-32 with their spinners & I dont need tht 5mm bolt for mounting the spinner. I doubt that but I will do a test fit and see. Else, I will simply take a standard 5mm bolt and turn the head a bit smaller on a lathe to make it fit in the spinner cone recess
