Yeah, later IM's have some really neat features, but you and I both own early cars, @Highlander356 (I'd feel much more comfortable here if we were on a first name basis- the screen names so many people hide behind are so impersonal), that are VW pan based and DON'T have the transaxle/engine location altered (or other later updates). Yours is swingaxle- if you should choose to, there are aftermarket trailing arm brackets you can weld in to you pan to convert to irs (I've put an irs pan underneath my car to be better handling), but emulating what Henry does now- moving the trans/engine forward is a major re-work. Another change from the original pan based concept that is common on IM's these days- 911 front suspensions. I've ridden in Bob Carley's 911 based car and I can tell you, I wish it was an easy modification, but I have what I have.
You seem to have a need for you car to be 'collectable' or special, and maybe sometime in the future it will be, but the great thing about these cars is they are meant to be driven (and not stored in a garage and ogled from a distance on a show field). If you think putting together an IM Registry is something you'd like to do, great- but in the meantime, get out there and enjoy the wind in your hair! Al
