I pulled them off, cut thru-the-wall slits, extended new standoffs to where they extended thru the BT about 1/2 inch or so. Then I used triangle stock on both sides of the standoffs inside the BT, using 30 minute epoxy.
Very strong now. It looks and works great! It withstands landings well finally.
If you need a copy of the destructions, let me know!
Hope this helps!

Looking at the plans, the ram jet to body tube joint appeared to be a weak point. I'm sure who ever built this followed the plans and didn't do any "beefing up" of anything. The rear of the body tube shows that it's had at least one very hard landing.....
