All I needed was a phillips screwdriver to take two screws out of the top panel. Then the two side panels pop off. Notice there are three click tabs on each side panel, and also that the top and bottom of the left and right panels, must be manipulated in a sliding action(front to rear facing the oven door front.) A good deal of hand force is need to accomplish this. Clean the old glass out, put the new glass in, carefully might I add, and reverse the above process. Just a little mechanical inclination will get you there. Good luck! I almost forgot to add that this job goes a lot easier if before all of this, you simply remove the oven door from the oven, by opening the door about ten inches to the point where it stands open on its own, then grasping it firmly on both sides and pulling up, with a slight jerking action. This breaks it loose so it can very very easily be removed, and replaced. Best of luck!
The oven bottom was warped and could not be positioned properly in the oven.
Removing the old oven bottom was easy...as it was already outside of its slots. Installing the new one was pretty easy. I placed the oven bottom in the front slots first...then the rear slots...no tools necessary.
1960's oven door gasket fell apart, actual gasket not available any more
Chose rubber flexible gasket with metal tabs. cut to size. unscrewed metal bracket on inside oven edge on 3 sides, slipped metal tabs between oven and metal and screwed back in. Done! Not a perfect fit but pretty good - better than no gasket.
I have worked in maintenance field most of my adult life and all aspects and to change the oven door gasket was no challenge what so ever. It took longer to find my needle nose pliers to remove the old gasket clips and then re-install the new gasket. Maybe 10 minutes total
