i guess its my turn to chime in.
i just converted to an alternator in my TR3.
i bought a duralast DL7127M for about $60.00 from autozone.
i figured i would
use the pulley off a standard generator to keep the wide belt. the hole in the
center of the pulley was larger than the shaft of the alternator. this meant i
had to machine a spacer.
when offered up to the motor i found the pulley was
about 5/8" too far forward to align properly. as luck would have it the front
mounting flange has about a 3/8" thick offset behind the yoke of the mounting
flange. its aluminum so easy to cut and grind away. the other 1/4" i machined
off the back of the pulley.
it was obvious that just a bolt through the front
of the alternator was not going to be enough to stop the alternator "twisting"
when i tensioned the belt. so i fabricated a little bracket for the back of
the alternator to fasten to the back of the standard "U" mounting bracket on
the block.
to install this i have to feed the belt onto all 3 pulleys then
bolt on the alternator. a real pain when i threw the belt on the I-5.
lastly
i had to cut away the bracket that holds the steering column when the car is
in its RHD trim. the alternator bumped against it.
i would recomend you buy
the wide belt pulley from this guy on ebay. im lucky that i have accsess to a
machine shop. and he only wants 15.00 for it.

im sure it would let you change the belt
without taking the alternator off the block. but i think you will still have
to fabricate rear brackets and check alignment. i have bought the part and
when i next have a belt failure i will swap mine out.
buddy Paul bought a
"bolt on" kit from some source. we found his kit also required repositioning
to align properly and it needed a rear bracket also.
im glad i did the
conversion as its been really reliable and i can run external components from
my cigarette lighter as its now negative ground.

Geo,
The battery was new at the restoration ( she has not been driven in 4+
yrs :-(
so it will be replaced ), as for the night, yeah being in the
northern
reaches, night driving is more prevalent especially in spring
and fall
obviously :-)
Now, that being said, if I was driving all day then the battery
was well
charged etc, stop and go, short trips etc, not so good. Big a$$
stock
starter comes to mind at that point :-)

I think I have
similar current demands incl radio, tape deck & H4
headlamps and I have never
had an issue with the dynamo keeping up.
My night driving is seldom more than
an hour or two and perhaps that
depletes the battery some but with most of my
driving in dry daytime
conditions it recovers fine.
Perhaps the issue is your
battery -- does it also date from '02?
