Exhaust Modification
This goes under the "I wish I knew
then what I know now" category. On a '75 TR6, there's an exhaust
hanger bracket that attaches directly to the rear of the stock
transmission's rear mount. When you install the Toyota 5 speed
you don't have this to attach the bracket to anymore. So it's
time to improvise!
What a
grimy, oily, filthy mess this is! That's the old
tranny up
top . The bottom yellow arrow shows the bracket that you can't
use anymore. The top arrow shows the attachment
point |

So I had to
improvise a little to get a nice secure mounting point for
the pipe's support. The U shaped piece of metal is the stock
bottom piece. Above the pipes, in the left photo, is a piece
of 3/16" steel bar that I had lying around and then
there's the 5/16" threaded rod that goes through it all. The
threaded rod then goes through the bottom of the original
rear tranny bracket that you re-use with the conversion kit.
Getting that Nyloc nut on the rod was a challenge requiring
two people and an assortment of wrenches and jam nuts.
Basically, I jammed 2 nuts together on the rod and while my
wife tried to hold the Nyloc nut steady, I attempted to
thread the rod through the steel bar, into the tranny mount,
catch the nut and screw a sufficient length of rod into it.
If I knew this before attaching the tranny to the rear
mount, it would have been very simple to just drop the
threaded rod in from the top. Regardless, it makes for a
real solid support for the pipes.
Yellow
arrow is tranny bracket, orange is the metal bar,
blue is the threaded rod and green is the stock
bracket. |
