Defender 110 rear X member bolts?

Hi.

I'm in the middle of changing the rear X member on my 110. The X member to tub bolts were a bit of a pain to get out. Some of the captive plates are now scrap.

I looked on paddock and eBay etc, but can't find replacement captive plates, all the bolt kits are nuts and bolts. I'm worried the the lack of the captive plates won't spread the load, and lead to the rear panel cracking.

Any advice?

LR Direct do them. LINKY
For a little more cash YRM do the plate with stainless bolts/washers ANOTHER LINKY

Mega, thanks, I didn't have any idea they were called Nut Plates.
