I had a 2.1 crewcab and found that any dual port double carb set will work
fine from any hot vw.  The manifold bolt pattern is exactly the same.  Any
set up for a dual port bug motor will work fine, just dont under carb the
motor.  Same for the distributor, I used an 050 with electronic points, or
lack of them.  Engine felt more powerful than the FI, just had to reinstall
for it to pass smog.
