I had usps loose a package for a good month.
I got a refund, then one day it showed up...

the seller told me "wait longer",
Me: it's been a month, time to find another seller.

USPS: :crazy:


I'll still never forget when i had them route a pew all around the country.
it was a good week + late.
I started thinking it was stolen in transit.
I've had packages shipped via USPS just vanish forever more than once or come open with no contents. I've got two instances that immediately come to mind and both involve a couple of members on TYF :crazy: Luckily none of the items involved were overly valuable but the USPS is just so inept it's ridiculous. At the beginning of the year a couple of bills I sent through the mail took over 6 weeks to get to their destination which resulted in late fees being charged to me. At that point, I completely swore off the USPS and will never use them again and less I have absolutely no choice.

there are a few locations that come to mind, every time I see my package held up there i begin to worry.
IL, NY, and i think KY was another bad location...

And i got my pistons!
did a quick mock up with one of them, perfect fit on the rod bushings.
Roughly it looks like flush with the top of the block at tdc.

One thing that i wonder about, quench
looking at most gaskets available like Felpro, compressed thickness is something like .043 - .045...

Ugg, so it looks like i need to rethink my head gasket.
i see some copper gaskets are available in thinner options.

Or i see about having the brand new block decked to bring the height down.

and the pistons appear perfect, if i were to raise the height of the piston. I'm not seeing special order options.

so i'm thinking, get the crank and the balance done.
assemble with new bearings, and double check the height...

if i remember, i need to bug the machine shop when i drop the stuff off.

Anyone have any experience with Cometic head gaskets?
I see they have a nice selection of different thicknesses with the mls type.

USPS lost a firearm I was waiting for once. Tracking said it was delivered, so I went to the post office the next day and explained that I was an FFL and there was a pistol in that box. They were back at the counter with it in less than 60 seconds. Funny how the tone changed once I said it was a firearm, and insisting it was delivered became knowing exactly where it was in their building.

I've been awaiting the arrival of GMT900s to my local pull-a-part yards, so I could do some more customizing. I FINALLY got an alert of a new arrival today of the first one to show up close to me. Then I take a look:eek::eek::eek::

What was the point? I mean there's almost nothing left. I suppose someone could get a rear wiper arm, or bumper cover.
