The advantage (or should I say disadvantage) of
having a few later TR7’s, when restoring a pretty early TR7: I know most of the many detail
changes and upgrades done by the factory over the circa 7 years these cars were
produced. And as I do have a fair amount of spares from later cars it is always
a good thing to apply some of these changes to my ’76 car.
One of these changes was the prop shaft bump
stop (UKC8268). In the picture above you can see the later variant, which
was retrieved earlier this year from one of my spare shells (a 1980 DHC),
before and after cleaning.In 1976, when this car was produced, this part
wasn’t fitted yet. And as a result the mounting studs welded to the
transmission tunnel were also missing. Below are a few detail shots of these tiny
parts. The first picture was taken from below, from the part’s donor shell. The
second picture is taken from the inside of another shell. Clearly visible in
this picture is the way the two studs are mounted to the rear of the transmission
tunnel.
I should have removed the studs and mounting plate
from one of these shells in order to weld them to the ’76 body. But I simply
forgot to! And as welding to the still freshly painted shell will not happen, I
had to look at an alternative. Turned out to be pretty easy. First I had to collect
the necessary fasteners. I went for stainless flat domed Allen headed M6 bolts
and nyloc nuts.
Final stage was marking out and drilling the two
mountings holes and dropping the bolts in from the top of the transmission
tunnel (using plenty of non-conductive grease to prevent contact corrosion). At
this stage I had expected I needed an extra pair of hands to keep the bolts in
place while putting the bump stop in position from below. I needn’t have
worried. The bolts slipped into the holes quite easily. Even fitting the
washers and nuts wasn’t a problem. As was tightening the nuts, using an Allen
key wedged against the rear bulkhead to prevent the bolts from spinning while
they were tightened from below.And while I was at it I removed the wiring clip
I forgot to remove before painting, touched up the damaged area, and replaced it
with a nicely refurbished clip.
As fitting the bump stop went smoothly, I had some time left to look
through my spare parts in search for some parts needed to finish both the boot
area (rear light bulb holders) and the front bumper (side lights). A few hours in the shed well spend!
