Depends what gold pan it is?
The very early cars had fixed shock bottoms that didn't slide out.
Next were the the gold tops, with slatted bottoms
Then the later black plastic tops which were on the later champ editions
My guess unless you had a very early car it would be the middle option, these regularly come up on ebay in the states
