Can't really answer your build questions cause I don't own nor have I built a glass 33/34. But there are people here that have and they can be a tremendous help to you on this issue.

As for registering a streetrod in California, again I do not live in CA so I can't speak directly on the subject, but from comments and statements that I have read here and on other sites, it can be a difficult and frustrating affair. But it can be done and people do it every day. You will need to keep excellent documentation (receipts, pictures, etc) cause the DMV will want to see everything. Again their are others here who can walk you thru the whole process.

Good luck with your endeavor, the end will definitely justify the means.
