To install a bug IRS trans in a 69 single cab that is IRS the only thing to change are the nosecones and inner CV's right?

Alan,
The nose cone on the bus and the Bug IRS
are more than "nose cone different". The
selector shaft is at a much lower position on the Type 1. (it will be pointed below the
bus shift tube).
It will also be quite different in gear ratios. Your bus has a final ratio of 4.41
(thats the number of times your engine turns
to the times your drive wheel turns.) The
Bug IRS is 3.67 or 3.60.
I don't know about axle fitment, but the rest
of the circumstances make it NOT a good swap.
The single cab is still quite heavier than
a Bug. The ratio does work when the horse
power doubles (as in Type 4).

Thanks Joe, This is for my son and he wants to run low profile tires in 15" Empi style 5 spokes. I thought that a bug IRS would get the ratios back to a more normal one.

Alan When running 5 spoke Empis on a van care must be taken to back space the wheel to the drum. The bolt pattern is the same but the drums are physically different from the bug. I did it a few years back using genuine old two piece Empis. The rear drum had some splines on it that I had to take down with a grinder to make them fit up against the drum. At that point I thought that I had it made but on final torquing I cracked one of the wheels. I wish I could remember now if it was a front or a rear but it`s been over ten years now. My point is, proceed carefully and you`ll discover which one it is. I later realized that it could have been avoided with the use of spacers behind the wheels. Perhaps the newer one piece units are more universal and this is not needed. But it never hurts to know these things in advance. Good Luck. Bob

The wheels are repos by American Eagle and they fit fine. No backspace problems.I have some on my 67 bus and had to bulge the rear quarters just a little for tire clearence.
We are going to leave the stock trans in the 69 for now and see what kind or rpm it will turn if it is too high then I will adress the trans thing. Thanks for your responces.

Alan, sounds as if you have a plan. I have a comment. I would say that if you were after higher gearing (to compensate for smaller tires) the way to go would be with a later 02 gearbox. With power increases in the engines came higher final drive ratios in the trans(R&P). The 02 is a bolt in and will give better gearing.Keep in touch and Good Luck. Bob
