If you were more specific with what your car is it sure would be easier for others to help you! Assuming it is not a 1957 VW?, the 1962 Oldsmobile F-85 came with two different battery trays, Jetfire and all others. If the battery tray is corroded out often times one or both of the support brackets are too. If the tray is for a NON- Jetfire application, the end clamp/retainer could be shot too. Just what do you need?
That is certainly possible as the 61 and 62 Oldsmobile Service Manuals do not show pictures of the battery tray. The only picture that I have found is in the 63 Service Manual (attached again with a larger format). The four 62 F85’s that I have owned all had the bottom end retainer style battery tray.
I did not word that well. Both of our 62 automatic Jetfire and the one on our 62 4 speed Jetfire and the one I pulled from a 61 Buick Special are all 4 the same. I will have to look at the 63 Jetfire but I believe it is also the same. I have a 62 and a 63 Cutlass and both of them are the other style like you are saying.
