The aftermarket door strut brackets that accept the McMaster seals are really well designed and look great, however they have a lot of angles to deal with during the installation. Additionally, the cabin top also have a lot of fillets to work around. If those angles are not followed exactly, you will never get the screws to line up unless you oversize the holes. To aid in this task I decided to make a (2 time use) drill guide to get all of the holes in alignment. I say 2-time use, because I did not have the patience to wait for mcmaster to send me a tool hardened drill guide so I sacrificed a #10 screw to make a set of #40 pilot holes in the cabin top.
Getting the bracket and screw in alignment.
Taking off the screw head and finding the screw center.
Putting a #41 hole through the center.
Thankfully everything was tramed and came out center.
Drill guide in use.
Don't mind the positioning of the actual bracket, there is still some fiberglass to take off of the edge.
