viewtopic.php?t=5008&p=50714There are a few suggestions here and also a link to a previous thread. If you try forum alpine Renault (in French) there used to be a cross reference list there too.
However...It's not as easy as you'd imagine...yes everything comes from elsewhere (usually) but often the Gta is the more common car now. That makes the other sources really rare. Try European sites as opposed to the uk as they can often help. We don't have that many old cars on the roads in the uk outside the classic car scene. Other countries run them for longer, so spares are easier to get. Blame salt and company cars for our relatively short car lives in the uk.
There are many nearly the same parts (like Citroen bx front calipers for Gta rear....apart from all the seals and the handbrake arms).
Renault espace is also a good source of some bits. Try getting the engine code and starting there too. The major prv engine types atmo, turbo and a610 have sisters in other cars so some parts can move over.
Suspension is mainly espace and ren 25 at the front, bespoke at the rear.
