Re: [AMC-list] BBD Carburetors and HEI--Dist Gear

[Matt Shumaker <mshumaker@xxxxx>]

What Jim Blair wrote sounds correct.  I made this swap in 1999 or so I 
think.  (Where does the time go?)  So my memory is not exact.  I may 
have bought a purpose-made distributor gear that fit on the GM 
distributor.  I recall that the distributor gear I used was a tight fit 
with no wobble.  1999 was a time when many of the AMC cars with BBD 
carburetors were still on the road, so the HEI conversion had become a 
sort of cottage industry.  I bought my conversion from an online source 
that had been linked from the old AMX-Files website and list.
