First time posting so I hope I do this right

I'm looking for:
1. Specific Sampala fic - Dean figures out his brother has been turned into the impala (again?) Sam on the other hand really likes it when his brother gets under the hood or in his trunk. Going as far as to makes excuses to get Dean there.
He tries to hide the fact that even though he's a car he's still turned on, leaking oil and such, which makes Dean more worried that something's wrong. Sam eventually gets back to normal (not sure if this was by Gabriel's doing or not, also I think Sam tells Dean what was going on about his time as a car) which leads them to having sex.

update: FOUND in comments


General Wincest/J2 fics - looking for any: (I like bottom Jared/Sam more, although I won't say no to bottom Jensen/Dean)

2. Mpreg, A/O/B, Werewolf/Knotting - the longer the better, but I'll take anything,

3. Time Travel - fics like - The Time-Traveler's Brother by gretazreta but any is fine,

4. Merman - where one or both boys have/get tails,

5. Tron - any fic but more along the lines of Tron Legacy,

6. Sam with wings - growing wings (nothing to do with Lucifer) &

7. AU fics that include Jess dying and Dean not coming to Stanford like he did in the pilot.

I know this is a lot but If anyone can help me find some of these that would be great, Thanks in advance.
