'94 'Boid and Junkyards

Re: '94 'Boid and Junkyards
I belong to '94 TBird LX V8, 61k mi.
No, I'm not gonna put the 'Boid in the junkyard. Not yet. I am occasionally tempted ... :-)
True or False:
If ya call a junkyard and ask if they got a part for, say, a 1981 <whatever>, they'll likely say something like "We don't keep 'em on the yard that old. They're all crushed and scrapped".
If ya call a junkyard and ask if they got a part for, say, a 1994 <whatever>, they'll likely say something like one of the following:
1.) Yeah, we got one. 2.) No, but we get 'em periodically. Try next week. 3.) No, but whasshisname over yonder might have one.
Suppose, now, that a Po' Soul was financially challenged, and needed to run his ThunderChicken until the wheels fall off (the TB -or- the Po' Soul, whichever comes first).
Question becomes "What parts, on the '94 'Boid with 4.6 L and 4r70w ("SHIFT, DAMN YOU!!!") tranny are likely to require replacement in the second 60k mi. that the PS hopes to get outa the vehicle"?
Already the seal between the plastic and aluminum radiator parts appears to be failing. Dunno if this would be a good candidate for junkyard purchase: maybe buy a rad. cheap and install new seals?
What is it likely to take in the way of repairs to keep a '94 TB LX V8 (that is flawlessly maintained and always babied) reliable from 61k mi. to 120k mi.? How much of it should a Po' Soul be thinking of buying this year or next and before the junkyards start crunching everything older than 1995?
And when is the 4r70w likely to fail if it is given the easiest usage and the best maintenance possible? I already figger it'd cost maybe 3 times the value of the car to rebuild at, say, 100k mi. I've been putting maybe 4k mi. per year on the car.
Any/all help/advice much appreciated.
Prost, Puddin'

that I think is a trick loaded question. I have seen the 4.6/4r70w combo still runnin with 650,000 miles on them in a few limos, and I have seen a few of them also blowed up with 50,000 miles on them. maintenance is a big issue. motor oil and filter changes every 3,000 miles and trans service every 35,000 miles does wonders. but 50,000 miles with no fluid changes normally leads to sludge in the motor, and burned up transmissions

You mean the 4r70w Q. Wasn't meant as a trick Q.

LC Town Car limos? How much might they have spent on repairs? Do some folks rebuild 4.6's? For that matter, are -any- motors (to speak of) rebuilt nowadaze?

That sounds like abuse. Many limo drivers (maybe most everyone not driving something they've paid for) are not overly concerned with repair costs and the like?

I'm 100% up-to-snuff.

With pert near any vehicle, I 'spect.
Still don't think it's a trick Q. Should've mentioned that the 61k existing mi. are about 80% city miles.
Cheers, Puddin'
