Ooh, good idea! Thanks! Here's a quick mock up keeping the trans at 15mm higher, but moved forward. Not sure how far forward I can go if I run a gear reduction like I was planning, but it would definitely safe some interior cutting!
As shown, it looks like it would protrude about half as far back into the interior.
What I also need to consider is where the speaker box will go. Don't most people run the speaker just behind the grill? If so, moving the trans up/forward will kill my space. I need to look into my options for speaker placement.
FYI, I don't know that I'll go with an MFU from Tamiya. While that would be great, I may opt to save some money and go with an alternative sound generator. As always I'm open to suggestions, but was most seriously considering this one:
