I was just wondering if there was a rule of thumb. For example, why are all center console mounted on the right and not center. I get spacing. Like how much weight is needed in the rear.
You are about to change the rules. as in altering how it was built originally.
So just do everything in a safe and planned manner.
Paying attention to things like dwco5051 said keep the strength in tact, If you have to remove it... replace it with something in an acceptable way or method. Be Smart about it. if you don't know, the folks here will help guide you.
Things like you may be standing up in the center now in navigation.
It was designed to be sitting down and at rear. It's a little narrow, So you need to pay attention to that and not build a death trap or rolly polly.
Thats why I said do the float tests and figure a lot of this out yourself, as the guys guiding may... or may Not have built exactly what you are planning to do.
And someone may chime in,. in a week or so that did this exact thing and it may have been a success or a total Flop.
This is a very knowledgable forum.
And after a few float tests, you could find this is.. or is Not a good idea.
I'm building a modified custom also, but completely different than you.
So I kinda get it. Making it your own.
Just keep it safe is the first move. Be double sure.
