Newbie owner with multiple questions Options

[devil]

My 914 is finally here! The condition is not as bad as I feared, but is also not as good as I hoped. But as it was always going to be a project car, I’m not yet having much too buyers remorse.

Originally a yellow car, but has been painted red (horrible quality, even the side markers have not been removed, only taped up and the painted etc), but by the looks of it, the longs seem to be pretty solid and most body panels look good. I haven’t removed the rockers, but from my first view, only surface rust. Has travelled from California to the Netherlands and now in Estonia. There is something fishy with the front end though – the hood is not flush with the front wings and also the lights sit somewhat lower. Could be that the front has been crashed and then badly rebuilt, but I’ll tackle that much later – first must get it registered and get it running.
The engine runs, but I have no idea when the oil was last changed etc, so not trying too much at first – will replace the oil and see what’s what.

Of course as a new owner, I have multiple questions and hope you can shed some light for me:

1) Did 914s come with two separate/different keys for the doors and the ignition from the factory? I have 2 keys – one opens the driver door and one is for the ignition, but neither work for the trunk and the passenger door. Hoping that the locks can be somehow unified to work with one or two keys at some point.

2) As I’m located in Europe, can someone recommend a good source for parts? Especially interested in body parts (I know of 914rubber, but as they are in the States, I’d like to skip on paying too much for transport overseas).

3) According to Porsche’s own materials, the correct oil for a 914 should be 20W-50 (at least the Classic oil has those numbers). What’s your take on this? I will not be using the car in the winters of course and the summer here usually doesn’t go about 25C.
