[TR] Bolts for Spitfire Hardtop?

[Bud R]

Now that it's no longer a Christmas decoration I was playing with the  
new Spit and realized the front on the hardtop is not bolted down at  
all. Good thing I didn't take it out on the hightway first. Can anyone  
tell the size (length, TPI, etc.) bolt I need to look for?  Looks like  
four are needed of the same size.  First Spit hardtop for me so I know  
little to nothing about them. A pic would also be great.

I'd like to keep the hardtop on for the rest of the winter and not  
take it off in order to figure out the bolts needed. Also is there an  
attachment to the hardtop (in back /sides and above where the rag top  
rack bolts to the tub) that looks like a hook bolt of some sort should  
be holding it. But they are no where to be found if they were ever  
there. Any ideas on what those bolts look like?

Thanks
