Later
style, can be used with stock 38mm SUs or the larger
46mm 4-bolt SUs found on the 2000 roadster. To do this
you also need the interconnecting linkage piece for
the 46mm carbs, and will have to have it shortened a
bit. Typically the bore holes in the manifold are
enlarged (tapered) to match the carbs. It will also be
necessary to make a new inside plate to our air
cleaner, or use separate air cleaners. The original
air cleaner is a high capacity unit and should be
retained if at all possible.
Although
this manifold will fit on a 1970 1600, it lakes the
center mounting and ports for the emission valve that
70s came with. Only non-USA 70s came with this
manifold.
This
manifold has METRIC threads, so you will have to
locate these if using these to replace a manifold that
originally came on an engine # lower than
R-40000.
