newbie--914 ownerr for 36 hours '75 1.8, 26 years in storage. Now what? Options

[almus]

Greetings,

I am a newbie 914 owner. Said green 1975 1.8 has been
in garage in northern NH since 1984. There is rust,but it is
surprisingly not that bad. Purchased for the princely sum of 500.
Interior good. battery support is rusty but doesn't appear to be
real bad. Looks to be about 62k original miles.

Gas tank contents have reverted to primordial ooze.
Gas tank cleaning kit? or radiator shop? Donor?
Oil is clean; must have been changed just before being
parked. Can't open rear trunk

I am concerned the entire fuel system may be shot.
My thoughts are to find a rusty donor car to
scavenge.

I have some newbie questions.

Will any 914 motor fit in my car? If I get a 2.0 donor,
are there any years that *won't* fit because of ???
(transmission? mounts? etc?)


Any local (to me) gurus willing to show me the ropes?
I am in south east New Hampshire.


Thanks.
