993 calipers on late 944 NA spindles?
 

Hi guys, I need a little bit of help: I have the opportunity to buy a pair of front 993 calipers (part numbers 993.351.421.20 / 993.351.422.20) pretty cheap and I wonder if it's worth considering..
I mean I'd like to know what's involved in making them fit. My front spindles are '89 944 NA with original discs and calipers.
What parts would I have to buy/change, is there any machining needed?
Also, do these fit under 17 inch rims?
Thanks,
Alex.
