Searched on here for a decent thread about what is involved and I can't seem to find one, hence me starting this one.
As my usual techy requests go I'd like to hear from someone that has done it or has a clue and not speculating, i can do that myself.

To start, I have a few questions that I need an answer on;

4x4 ABS, how does this work if converted to RWD, do I use the original outer CV's and keep the 4x4 hubs? Also, brake kit won't fit if I change the hubs to 2WD items, and i'll need different wheels as the offset will change, so can I run the 4x4 hubs front and rear?

Sump and starter, if I want to bolt up a T5 box do I need to change the sump, if i change the sump will it clear the crossmember?

Rear shafts and diff, can I run a 4x4 rear diff and shafts with a rwd prop and box?

I've heard of so called pikey 4x4 conversions, doing it on the cheap, I don't have a problem with doing this as long as it's safe and it drives ok. i.e is it possible to remove the inner cv's, shafts, leave the outer cv, disconnect the front prop (leave the front diff in place) and change the box and rear prop and exhaust?

Be good to hear your experiences.

I want to have the car 4WD with a decent box, but RWD'd would be a stop gap to use the car over the summer and possibly take it to croft/long distances and not worry about the box, so I'd be changing it back to 4x4 again, I'd ideally not want to change the rack/x-member, hubs etc etc etc etc all for RWD bits to have to take it all off again.
