rick,

if I was living in USA or even better in Cal I would speak to lynn as well. he is a nice guy to deal with, but with the backyard mechanic fixes that are proposed to fit his wheels i cannot agree.

I believe most wrencheing guys in this forum know how to tighten a bolt or nut, although some do not seem to bother too much in bending wheel studs slightly to straighten the stud-bolt.

that will cause stress in the root of the wheel stud thread. would one do this to a rocker arm stud, or main bearing bolt? I am going 160 mph frequently. I rely on my wheels.

my solution is
1. buy a similar set of stud bolts which can be modified (retapped, cut, milled) you may find a cylindrical one at the local wheel shop (4 hours on a lathe).

2. as you proposed, fabricate your own and mill a regular 9/19" hex to it (6 hours on a mill?).

3. ask CAV (GT40) in Cal if they sell you a set of theirs. make sure they fit into the wheel.

4. for jaguar suspension users, press the original stud out and bolt the adapters on with 1/2" allen capsrews with nut. they feature a head diameter of 3/4" fitting perfectly into the wheel. there should be enough space for a nut. I checked my XKE suspension
cut the taper (90 degree!) onto the underside of the head.

one drawback: lynn's old design of adapters were centered on the hub via the lip on the hub. now they are centered by the stud bolts. should work with the undercut allen srews though.

PS wheels:
I wonder if their holes are just big enough to compensate for slightly bent stud bolts.

and yes, there were definitely stud bolts which worked. I had a set for a customer in 2001.
in 2000 I battled with stud-bolts getting bigger in diameter when applying torque, some also cracked. they were green-brown.

the lates silver ones had the wrong bevel/taper and were not tapped parallel to the outside. slightly scew causing the stud to bend when applying torque.

my wheels take up garage space since 8 months...
