Dynamo / Neon Mame / Flyercade style cabinet drawing plans

[myarcadeid]

I haven't posted much here, but I've already built a Lusid style cabinet.  I'm considering building another one similar to Knievel's Neon Mame but I'm having a hard time finding a dimensioned drawing and I don't have access to a Dynamo cabinet that I can measure.  I did find this post...

and have used the information from the flyers (thank you Crowquill!!!) to try and make one.  It seems to be a popular design but no one is willing to post an accurate dimensioned drawing.  Anyway, I have no CAD skills whatsoever so this was done in Excel using the grid as graph paper.  Each square represents 1 inch.

I'm looking for some constructive feedback here so please let me know if this looks totally wrong, or if it's pretty close.

Thanks and I hope it helps someone else!!
