Bit of an indepth one here

Following my heavy handedness and a VERY rusted in bolts it looks like I might have to splash out on some second hand bits for the Project.

So.....
Will Gti front suspension legs COMPLETE with discs, calipers, struts n springs etc go straight onto a 91 Driver ?
Will the driveshafts fit ?
and if so which will be best, and 8v of 16v one ?
Many Thanks in advance
