After minor modifications have been made to the original transmission
motor mount housing, Dodge Dart upper A-arm bushing (1963-73), costing
about $3 each, may be substituted for the original Lotus mounts. This
modification requires 2 new ½ inch motor mount bolts and a one inch
electrical conduit coupling for parts. The tools required consist of gas
welding equipment, a hacksaw, round files, and a vise. The following
describes the required modification steps.
Place jack under the transmission and then unbolt the mounts from the
transmission and frame. Then remove the rubber inserts from the mounts
by heating metal portion of mount with the torch.
Fit a 1 1/8" section of the conduit coupling inside the original
mount housing (will require some filing). Note: The electrical conduit
coupling must be steel and will have an inside diameter of approximately
Position coupling as shown below and weld both inside and outside of
coupling to original mount.
Carefully file excess weld from inside of coupling so that the front
end bushing is an interference fit.
Drill the frame mount bolt hole to ½" (this is about a 1/32"
