I too have the 1.8 CVH engine from a complete donor I had, makes for an easy swap to Zetec later on
( theres a few parts from the CVH engine you,d need when installing a Zetec & it also has exhaust exit on same side, saves having holes in both side panels.
You won,t need the petrol tank ( too big ) but maybe keep the sender if you intend making your own tank, if you get a CVH engined donor the fuel pump is part of the engine.
Won,t need the fan or Rad...again too big
Most folk get a new propshaft made to measure, tho keeping the donor shaft might raise a few £,s to sell it on.
The only thing I can think of that you haven,t mentioned about keeping is the Speedo cable.
Best wishes for your build
cheers
