I Have Seen A Insert To Install Three Guages Into Cassette Holder Space On Ebay. Anybody Know Were To Buy This Insert Thanks In Advance

 

I believe RK Sport had it, they don't sell it anymore now, you'd have to find one used on eBay or make your own.

 

I am having this made. This is a mock up for my nitrous set up including just one gauge but he can make whatever you want. He is also going to engrave next to the switches (ie Nitrous, bottle warmer etc) He has textured plastic to match our interior, but I went with aluminum for a different look.

I'll post another picture once the panel is actually made which s/b in a day or two.
