I'm wanting to change out a Lowrance 520 for a Lowrance HD7 on my 2009 Triton 21 X3 and would like to find the dash that has the right size hole instead of cutting mine out.I've looked on e-bay and Amazon,but I've heard of some good dealers to order parts from,but can't remember the names.Thanks!

Try Bass Boat Technology for a plate that will cover the present cut-out and will allow for you to mount another unit. Ask for Vans and tell him shut-up-and-fish sent ya. He will take great care of you.

I worded the topic wrong,I want to mount it in the dash where the 520 is now,I don't need a plate but the dash with the hole cut out for a HD7.Thanks

Not sure you will find an exact replacement with cut out you desire but if anyone can have anything would be
