Building dash panel without breaking the bank

[Pete357]

Just wondering if any one has any answers on if there is a way to build a dash panel without breaking the bank. I have done a bunch of searches and seems like the only info out there leads to really expensive options. I was just wondering if there are any tips out there on modifying a stock dash panel with aftermarket gauges. All of my stock gauges are shot. I don't need a fuel gauge as i have a fuel cell with no sending unit in the bed of the truck. Previous owner had a 5" faze tack on the dash and 3 2-5/8" summit gauges for volts, water temp and oil pressure mounted down low on a custom panel. I really want to clean it up and get my gauges on the dash but want it to look clean and neat. If there is any way to use what gauges i have i will just have to purchase a speedometer and a boost gauge yet.
One option i was looking at was ditch everything that sits behind the plastic dash cover and just size up holes in the plastic piece to mount up my gauges but then how to i do turn signal indicators and what not. Any suggestions?
