I got the cowl from Stan's Fiber Tech which is now AeroFiber Tech: http://www.aerofibertech.com/index.html Looks like it's still available. I did remove the cheeks, even with the firewall and needed to cut off some of the back of the cowl. Other than that it fit great. I side mounted my OS 91 Surpass which required a lot of cutting since the cowl is fairly narrow. If you mount your Saito inverted it should work a lot better. That's what I'd do if I had to do it again. It's been quite a while back but it seems like I added 1/2" to both the elevator and rudder. It also seems like a moved the landing gear forward and have even shimmed it in back to get it more further forward. I put in a 16 oz. tank which was a mistake, since it already had a tendancy to nose over. 12 oz. is plenty. I'm going to rework mine when I get a chance and put a 12 oz. tank in and work on shifting some weight back. It's a great flying plane.
