Help - Spot Lights

I bought a 1974 Series 3 last year which had been butchered somewhat - mini metro seats etc but she is slowly coming back to being something like she should be.
My problem is that the front bumper had been extended with 2" box section and has two spotlights fitted. I replaced these with Ring Rally Giants, the only ones I could find with a "U" fitting which would take a different, longer bolt. The fixings are very poor and the lights keep coming out of the housings, it's only held on with a small plastic tab and a screw which strips out.
Are there any spot lights which have either 2"+ bolts or at least the capability to take 2"+ bolts which I need to fit tthrough the section. Most "Universal" fixings just fit through a standard bumper.
I shall not by any more Ring products - the modification to keep the lights in requires copious quantities of sealant I am sure the Subaru Rally team don't have to do this!!

Pictures speak a thousand words.....

I've used Ring lights for a long time with no problems what so ever. In fact Mucky is running a set of 4, and I carry a pair as spares. The Std spots have decent-ish brackets on - mine use a 1.5" bolt with a steel bracket. It's no hassle to replace the bolts.

If you use chemical metal to replace the stripped screw lug, it'll last a lot longer.

If your keen to fit decent lights .... go cibie or piaa.

Thanks DirtyRhino. Will check them out. Landy came with Wipac lights originally but I can't get them anymore.
