944 to 996 Turbo conversion?

[Evil Sid]

I have a complete early 944 brake setup on the front of my 1303 with 944 stub axles.

I have sitting in my garage a set of 996 GT3 Mk1 calipers which are the same as 996 Turbo calipers AFAIK. Can anyone advise as to a straightforward conversion I can do to fit these calipers with any disc I can easily source so they will fit under my Porsche Cup 2 7x17" front rims (so presumably 330mm discs are my max). Do not wish to have spacers on the wheels as they are out far enough.
Are there any radial mount conversions available to do this also? I can get the 944 to boxster rear conversion mount but I assume this is useless.

Thanks!
Sid

sorry forgot to say I also have the rear calipers same as the 996 turbo in case it is easier to do the conversion with them...
