You either need some kind of loom and ecu to suit the engine and cut it back to bare essentials
Or you create your own loom and put a stand alone ecu on it. Both are time consuming but one or the other. There is no real 'different'
Get yourself the gearbox sorted before worrying about the speedo, you can drive without it if you really had to but there are options once its in and you're ready
Driveshafts will be custom, no avoiding it. Unless you're having custom wishbones made to take suitable hubs and some cinquecento angled type shock mounts to avoid serious top mount angle, to match the longer shafts
Get the engine in the hole first off
All mounts will be custom, can be done properly without touching the chassis rails
Get your gear linkage in
Get your driveshafts measured and made from there. A properly made "cut n shut", I refer to them as 2 piece, driveshafts have withstood up to 200lb/ft from what ive seen this far, beyond is an unknown for me. But they're good for testing the length, lock to lock, full compression and droop of the suspension to make sure they turn the wheels without falling out or colliding with the CV casing. Then take them as patterns to have some made up ready
Only once you've got that far do you need to worry about the rest
