109 ex mod 200di conv. easy?

Hi again all, after the earlier post about my engine dying and all your responses, I think the 200di would be the best way for me to go. Now, after reading about a million posts and threads on here I'm confused.com again! Will it drop straight in a mod 109 or does it need a lot of fettling, engine mounts and the like? Will the manifold from the 2,25 be the easiest way for the exhaust to be mounted as it is? Should the engine bolt straight on to everything at the back? Also would all the wiring be the same? It has under seat fuel tanks so will the fuel lines be re useable etc? I know it's been covered loads but the more I read the more baffled I get? Also what would be a fair price for the lump and what would it cost roughly to get it fitted? Again thanks in advance for your answers, knowledge is power and I ain't got enough to power a fart. Thanks dan

Have you read the FAQ on the the glencoyne site? That covers it all pretty well.
