GTi exhaust manifold options/compatibility

Hi everyone,

Just discovered that the exhaust manifold on my 1983 GTi is cracked and generally looks like rubbish hence tried to find a replacement with no luck.
My question is what other cars/engines use the same manifold? I am currently not planning to replace the whole exhaust system with something nice as it just had a full replacement for the stock one ordered.

Engine code is DX and car is euro/LHD.

Thanks
Vic
