Pre loved Dave Platt Slash Short bolts and stuff.

Bought a very nice Dave Platt shorty slash (used) for my 04, lovely bit of kit I must say, however, it didn't come with the bolt, can I ask if there;s anything special about the right hand bolt (header side)? I only ask because it doesn't seem that stable with a regular replacement bolt and it has a fair bit of weight to stop from twisting and it's only really held with the grommet, one bolt and the head shield.
