I've gotten the motor back into the frame but concerned about this gap on the lower right side mount.

I've installed the the outlined parts

Front engine mount: 36, 17, 13, 17, 5, 5, 17 13, 17, 31
Lower Rear engine mount: 36, 37, 6, 17, 21, 21, 17, 39
Upper Rear engine mount: 40, 17, 15, 17, 32
In the parts diagram, I'm not sure about part combinations (14,1

To me it seems (20,16) is a the same as part 15?
likewise (14, 19, 14) the same as parts (21,21)
Can someone confirm? Or am I missing parts in my installation process?
also, its been 10yrs since I've last been on this forum. it's nice to see all the old names i recognized from way before (andy, etc..) thank you all for still being around and helping with the dream!
