1.1K is not much for anything that runs and drives.
When you say it needs a rear end, can you drive it with it making noise or the thing can't be driven?
If it's just noisy, you could probably drive it while awaiting a salvage yard rear end.
Heavy, but not difficult to R&R as an assembly.
The shocks are cheap and should be easy.
Just put a wrench on each end and break the bolts if they won't come loose.
If the newer engine and transmission are documented, then this might be a worthwhile project.
Just bear in mind that it will be a rolling project and not a turn-key daily driver.
It might not take a whole lot to make this old Expy into a useable daily driver as long as you're willing and able to wrench it yourself.
For the money, you'd at least end up with a good parts car, as Trevor noted.
