MR2 Spyder Convertible Frame Parts

I wanted to see if any members who have converted to a full hard top might have all the frame parts to use for a convertible top.  I have a project car I'm starting which was converted to hard top, but it was removed and sold before I took ownership.  Unfortunately they did not have the convertible frame either.  I'm looking to try and get back to the factory soft top (frame, parts, latches, clips) or if I have to, try and source another hard top.  If there are any details on where to get the parts or cars at wreckers to get them from, it would be appreciated.  I'm happy to buy a new top canvas/vinyl with glass replacement, but I need something to attach it to.  
 
Thanks,
John
