Allstar Performance Clamp-On Kits ALL99161

You'll need two. The inner diameter of the swivel is 1/2". It can be tightened at any angle. I cobbed together rubber washers and butchered grommets to eliminate metal-to-metal contact. The clamp itself and the swivel head are held together with hardened 3/16" Allen head bolts, all the same size. The tech support at Summit racing pointed out that these clamps were initially designed to hold the window netting on race cars and may be limited to the weight they can carry. I looked and measured and as the rack itself is held up by three points that putting on luggage or whatever up to 50 lbs is quite within reason. I can see by the way the clamp fits that it is not going to slip. The bolts holding the swivel are what would fail. They are more than adequate. The rack took only a half hour to install, most of that being used to figure out just how high on the roll bars it would be. The block of wood that Morgan supplies I used to hold up the rack at the fuel cap area during install. The car cover still fits, too!

Rockabilly John: many thanks. my personal 15 minutes...

Clamp from Amazon UK

This was the best equivalent I found from Amazon UK. Looks like they are used to mount lamps to roll bar / cages. Still a US supplier though...

OK, so following the trial fitment I have to admit defeat with these removable brackets!
Do not use the Harley brackets - the internal over centre pins are not strong enough to stand the lock loading -

Back to the drawing board 🤔

Having been back to the drawing board I've used the following £29

39mm Truss clamps eBay181375831564. £14
Stainless eye bolts £ 5
Classic mini rocker cover rubbers & washer kit
eBay 182132750918 £10







Stable, cushioned, removable and it works, the clamps stay attached to the rack when not in use, no drilling or badly designed fitting to install

The ones I've used are 8mm (because I had them to hand) but I'm looking at 10mm replacements which are the same bolt size to what's fitted on the truss clamp. - The bolt end must remain loose to allow the eye bolt to swivel once the lugs engage.

I've used additional red rubber washers top and bottom but may well use the other washers which come in the rocker cover kit instead.

I'm also looking at a tether for the spring pin so it cannot separate from the rack.

I used a pair of climbing nuts that looked good and will not come off!

http://climbing.about.com/od/climbingequipmentwords/a/NutsDef.htm

I looped them to the luggage rack so that when the rack comes off so do the spring pins but they stay with the rack.

One less thing to worry about.
