floor pan question

Got a few questions regarding doing the pans in 75 L bug if someone could help. I've seen people use giant saw horses to hold the body off where do I get these? Will it pass a nsw blue slip if the pans are pop riveted in? Also can you buy pans with the hump and rails installed ready to drop in.
Sorry for all the questions

no wont pass with pop rivets

u will have to make the GIANT saw horses

the 75 seat runners are different to early n later models so u will have to drill the 75 ones off and re weld into position

Haha fantastic...
