Engine swap, new K-member or swap kit??

Hey guys i've been doing some reaserch and recently found that there are engine swap kits so that you don't have to go and buy a new K-member. I am doing a slant 6 to a 360 and saw that schumacher creative industires (http://www.engine-swaps.com/) makes a swap kit so that you can use the slant 6 k-member and just use these special motor mounts. Has anyone ever used this kit?? Would you guys reccomend this or should i stay away from this?? Thanks a lot for you help it's greatly appretiated.
