Going to have to repair/replace the trunk hinge on the car this winter. It was repaired before.... but it failed in a different spot. I wonder if the trunk lid gasket was too tight and caused this failure?

I am planning on taking the engine out to make it easier to get in there and position it correctly and do a good job welding.

How many of you have done this repair leaving the engine in?

I am not an experienced welder and trying to weld it while bent over the fender and trying to even get the mig in there seems too hard.

I have already had the engine out twice since last Oct. so I am getting quite good at it.

If you don’t need it to be original, Jwest makes a bolt in trunk hinge kit.

engine in easy if you can spot weld, and now with McMark'd trunk hinge tool, can be retensioned easily

This was the method I chose.
They come with backing plates so the sheet metal is clamped and the load spread out over more metal than the welded bracket.
I also like that the pivot is adjustable to help fine tune the trunk lid position.
Definitely not for the 'originality crowd' but a good functional solution.

The failure mode isn't tension, but rust. Or more precisely lack of lubrication that leads to rust. Once the shoulder bolt wears out its lube, its the beginning of the end.

Hardest part was getting the old hinge bits off

I haven't done it (yet) but I believe the JWest set up is an engine-in job.
