Jumping ahead here but whats needed to fit the Favourit or felicia engine into an estelle 105 1986/7 vintage? ....Also have read that all models from 1984 on have the later type rear suspension? ...Be grateful if anyone can explain why at my age the thought of collecting the 105 is keeping me awake at night!!:confused:

You will need the 136 rapid manifolds, flywheel and clutch, iirc distributor, sump,oil pick up and strainer. these are the major bits. One or two nuts and bolts will swop from the other engine

As for the rear suspension , the semi trailing set up was fitted to the rapid and 130 estelles. to fit this you will need the gearbox to go with it and the gear selector rod as it is a different length
