I don’t think I can get the squeezer in there to dimple or to rivet so was wondering what options I may have
Any advice would be appreciated other than read the plans properly you dopey twit ��

Don't worry. You're not a dopey twit. Few play this game without making some awesome errors.

Can you provide a specific part number that you're referring to? That could help us give you specific thoughts.

If you're referring to E-01410 Trim Access Reinforcement Doubler (page 09-12), you can drill out the rivets holding the nutplates, dimple the holes per Step 2, then buck the rivets holding the K1100-06 nutplates.

Remember, to get into tight spaces, anything with sufficient mass can be used as a bucking bar. I once used the blade of a heavy screwdriver.

Tiny bucking bars like this 12.5 ounce tungsten one can be helpful. eBay is frequently awash with these things.

You can also drill a hole into a bucking bar to accept a squeezer die, like below. This can be helpful for setting rivets and creating a dimple. I used this approach a few times during the build. Double bonus: The hole in the bar can also be used over the shop head of a rivet you're trying to remove when lightly tapping it out from the other side.

To give you more ideas, here's an approach I used on the rudder to dimple the aft-most holes on the R-00918 Attach Strips. It's a male dimple die, a washer, a "close quarters female die" and strategically ground-down no-hole yoke (with a little tape to keep it all in place).
