Spare Tire Hold down

So I have a spare tire hold down. Yes, I have the longer stud for the 340 cars, but it doesn't quite reach my cup. Then after some reading, it seems there We're there 2 different styles between Standard vehicles vs the HI performance models?

A friend of mine is looking for one of these "cups" or "washers." Hasn't been able to locate one. Any ideas?
