Nice Video Pete! I've done this multiple times now. Not used the torch but have had to retrieve my built in nuts and JB Weld them back into place.
This is also a very good testament to how cheap and brittle the grade plastic used is... That torch isnt on there but a few seconds yet the plasti-chrome is near liquid form.
**Another repair I've made a couple times, and made it a little better each time is to the area INSIDE this spring.
There's a cross pin that runs through the center of the whole spring/latch release apparatus here Ive highlighted with 2 Yellowish Orangeish Gold arrows. There's a LOT of forces being enacted right here and its far enough from the two anchor points that, if they're loose at all, it can allow enough flexion to cause the spring to rotate out of position, to not do it's job properly...
What I did was cut a small piece of tubing to go in the void space: Inside the coils of the spring and Around the shiny center shaft pin.
The pin with the two YellOrangGoldish arrows.
So you're inserting a piece of stout rubber or plastic hose, that is just barely longer than the coil spring, long enough to fit the space(maybe .70" IIRC?) that is just barely smaller than I.D. of spring coils....... and has an I.D. of it's own that is just larger than O.D. of center shaft pin...
Said actions drastically reduce the rotational ability of the spring/release apparatus.....loose anchors or not
Hope I explain that in an understandable manner?
