yes apparently CA18 bolts straight up to L series mounts and 120y already has holes drilled for L series mounts as it came with L series in Japan so its pretty straight forward in mounting it. id buy a 120y and put one in after he told me that but then he also told me 120y's have a 70/30 weight distribution and 1200's more like 50/50 so im still dreaming of putting one in a 1200 when i get some cash flow.
