Help with clutch sm465 vs nv4500

[dragn91]

I went to install the clutch that came with my nv4500 into my k30 that i pulled a 465 out of i heard they were the same but the 465 clutch springs were loose and rattleing i pulled it and found this 6 puck clutch.. well there looks to be a machined recess in the flywheel so the stock nv4500 clutch does not sit flat on the flyweel. The 6 puck clutch is toast what are my options now i really dont want to dump much money in it because i think ill end up ls swapping it anyway. Do i have to buy a new flywheel or maybe just a new clutch like the one i removed? Any help appreciated
