[DMCForum] Re: Apologizing All Over Ourselves (Toby)

["content22207" <brobertson@xxxxxxxxxxxx>]

Hopefully the Forum will briefly look the other way...

Compared to the swirlies I've been getting on the List lately, even an
intentional barb would seem tame. No apology for tongues necessary as
long as they stay in your own cheek.

Somebody playing on Greg's ID just jumped all over my case on the List
AGAIN. For some reason I've developed this reputation as a mechanical
menace, despite the fact I regularly drive the same car I drove 23
years ago! Not many people can make that claim. And I do so under my
own care! No 3rd party mechanics involved. Who do you think installed
the new engine in the back of my DeLo? Somehow I manage to transport
myself in a fleet of vintage vehicles, the *NEWEST* of which is dated
1985 with 204,000 miles on the odometer. Gee whiz.

I replied to the "other Greg", but whomever is moderating this week
saw fit to delete it. Just as well -- the reply would probably have
pissed off somebody else, and my hole would just get that much deeper.

Chapstick, anyone?

Oh, Re: transmission coupler roll pin: Rob Grady claims this is a
common failure item. Discovered mine broken when I pulled the
transmission. No telling how long it had been like that (my coupler is
jambed on the input shaft, so the pair couldn't slide out of the tube.
Would bump into the crankshaft when installed anyway). Since I had the
bellhousing off to change my gear oil (easiest way to do that!), I
took the opportunity to replace the roll pin. Final solution was to
hold it over the hole with some mega long needle nose pliers and force
it through with an 18" screwdriver leveraged against the housing.  

I am a little hurt that you let my barb against Flint MI pass without
comment...
