The kicker is, those arms that I am bolting to are big cast things that wrap around the edges of the bulkhead, thus carying up that straight edge, just like you are doing, its not like my rear one is just attaching to a plate floating on top. The cast peices support both the secondary side and the chaincase side of the jacshaft, meaning, they were put there to hold the thing square, they rivet in place from halfway down the front cooler on the inside to about 2" inside the edge of the tunnel, I put a LOT more faith in them then in anything I can build.
I try to resist reinventing the whee, but those are already right where you are building the mounts.
as far as the fronts, I am gonna try to mock up something like the front half of the plates you buitl... more pictures to come as I continue playing with things. If I could copy your front mounts and then make a rear set like the one I pictured, I think I would be pretty dang happy. I also am woring on trying to utilize those two cross bulkhead bolts in attaching the front mounts, I feel like I can get some good strength out of using something like that., but just more to play with for right now.
I have spent a lot of time looking at my old rev I have as well and see how much easier it would be to build the mounts your doing in it, its definately the best option, on the RT, less then ideal.

Alright... I need to not try and post when I first wake up... I have no idea what im talking about.
I sat and stared at my sled for a while and think I have a good handle on what Im going to do. For the rear mount, Im just going to make a stronger/updated version of my current rear mount, but instead of just a sinlge tab up to each of the motor mounts, I am going to do one on each side of it. This will prevent the annoying torquing of the bolt throught the rubber, I did one after the fact on the clutch side moutn ,the only issue was, I was welding it onto a bent mount, so just holding it still, but out of alignment. Putting a little more effor into getting perfectly aligned brackets on the rear should help me quite a bit. Also, for the front mounts, I think I have made up my mind on the right way to do it. I have some aluminum road sign which isnt thick enough by itself, but im going to double layer it for good measure. I am going to build basically a plate for each side that comes up like the ones JTAB built... I think they will work out well. also going to run a throught rod to deal with the twisting and then build a threaded torque arm type deal from the extra holes on the top of the front mounts so I can pull on the front clutch side mount to help it resist flexing the mounts. Also, I have a good way to run a bracket on either side of the bulkhead going from the jackshaft area to the shock tower, acting similar to the delta box on the Rx1/apex, this should help deal with the twisting bulkhead factor causing the motor to come out of alignment.. now just time to build stuff and get pictures up. I definately was pretty half assed with my first set of mounts as far as making them square, so this time, a little more efftort will be expended.

some quick pics.. they need more attaching, and im gonna run parts of my old front mounts to keep the throught shaft from flexing, but you get the idea. they came out super exact compared to one another, not bad for a sawzall and a cordless drill. each side is 2 layers of sign material, I will have it welded toegether in about a month when I can get some help... still thinking on the rear mounts.
