In answer it depends.....
And the reason for this is down to several things.
-such as where the engine is located relative to the body
-same with the gearbox
Then what you plan to do with it body wise. You could make it look like a completely standard Series 2 or 3 SWB, although the wider axles will need some sort of wheel arch spat to cover the wheels in the UK.
Many 88 coilers fit a Defender style front panel and bonnet (rad moved forward like a 90, not inset). This is because depending on where the engine is actually located you may not have much room in front of it.
Defender wings and doors could also be fitted.
It would also be possible to make it look like a Series 1 88", either as a standard vehicle or as a trials style vehicle.
e.g.
Or you could make it look like a Tomcat.
