Thanks. I cut and drilled some angle iron that I pulled from a scrap pile. The setup feels plenty strong, but I may reinforce the back of the seat plate adapters where they extent out about 6" behind the seat platform.Like what you did with the seat mounting. You bend the L brackets or use angle iron?
SHOOT! Why did you have to go and post this? Now you have me thinking.....Door Latch Reinforcement
Cracking along the door latches is very common on these cars. I explored a few options to reinforce the metal along the door as a preventive measure against future damage. I decided that I could slightly modify a couple of repair plates and weld them to the inside of the door to increase strength. It is my understanding that they are originally designed to bolt onto the exterior of the door as a quick fix solution, but obviously that doesn’t look too great. I tested the latch operation prior to welding and the latch operated without issue. I’m not sure if I am going to use the washers, but if I do, I will probably paint them the body color. The countersunk screws included with the Scott Drake latch repair kit are much longer than the OEM latch screws. There are probably a dozen of different ways to do this, but the doors now feel much more solid when closing.
