Engine bracket question

Sorry for the waiting on a reply. So yes I’m using a V8 k frame. It’s a 904 trans I’m using but it’s not in currently. I was trying to deal with these mounts and getting my headers fitted before going to the transmission.4 I’m pretty certain the biscuits should be correct, I bought Trans Dapt ones for a 360, so unless I was sent the wrong ones from Summit I might be mistaken. Again I without reference I thought the gap in the bracket to ears needed to be filled in so I put washers in. If it’s not right I’ll take them out. The studs are not offset on the biscuits so I’m not fully sure what’s wrong. Right at the moment the only thing I can see to fix the setting into one corner is cutting out some of the k frame slot to let the engine sit as needed but I don’t think that’s the best option. In all honesty I wish I had stuck with the /6 frame and used Schumacher adapters but with them being over a month out for making adapters again and a guy giving me this free V8 k frame I should’ve spent the money for Schumachers and waited.
