Default LS7 Fast intake and coolant crossovers

I am building an NA LS7 with Fast lsxr 102 intake.
Want to connect all four steam vents, and am only finding the Kurt Urban kit (a little pricey) and this ebay kit.

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=131238137728&fromMakeTrack=true&ssPageName=VIP:watchlink:top:en#ht_595wt_1362
Has anyone used this on a combo similar to mine with any success, or what were the issues?

Yes I have done a search, just looking to see what else is out there I may not be finding.

Thanks for value add input.

I'm thinking the L92 front coolant crossover ( part # 12605716) will fit on the back of an lsx motor with a Fast 102mm. Its the only one that looks like it will fit under the manifold on the rear passenger side. I'm going to pick one up and see if I can get it to work!

Update: the gm crossover (part number above) works just fine on the back of my motor! I torqued the manifold down amd pulled it back off to see if it was hitting anywhere. Its free and clear. If you have a cathedral port fast102 this will work. Should work on the others too. Not bad for $40 in parts!
