If you have a model number for the stove or a stove thats similar lots of the parts are interchangeable with most of the changes being cosmetic for the different model numbers in a series.
I needed the little pilot light tubes for a four burner unit
this link shows an oven rack for the stove in my 79.
if you scroll down you see tons of model numbers that use this same part. you can see diagrams for the various models if you click on a model link, then you should reach a ton of parts for that model, the parts have diagrams you can check for a visual.
They seem more geared towards major home appliances but they had the parts I needed to get cooking again safely.
Hope this helps.
