anyone use 90-93 mounts with b series in crx?

this guys page shows how to use integra mounts, and you just have to slightly relocate two of the chassis mounts. Since you can directly use the drivers side and rear mount, It should theoretically put the engine precisely where Honda intended. If you have two in place, then the engine is lined up for the other two ya know? I have all of the mounts for a 90-93 teg, and its better than the alternative of getting $500. Hasport mounts. So if I take all precautions into consideration, and make everything set right (axles in place)before having the mounts rewelded does anyone have any reasons I shouldnt do this and just get some poly inserts?
