Rafael used to occasionally offer Speedster parts - like a folding top assembly - on ebay. I think back then (2011) it was $499 complete? Would be interested to see if you are going with that. Would also like to see his interior kit.
Here's photo of Rafael's top frame (is that him fitting it?):

An inexpensive source of parts is http://vintagespeedsterparts.com/ - they have a great catalog with pictures at their web site. S&H is a flat $15 on most items. They have a sale now on rear license plate lights ($83) and head lamps ($22).
Here's already shortened pan on SAMBA - '64 swing axel. But NO TITLE for $350. Its not too far - Illinois. With a bill of sale perhaps you could get TX title. http://www.thesamba.com/vw/cla...etail.php?id=1941821
Same guy has unfinished Speedster for $8200.

Look forward to following your build!
