Bus Conversion Windshield Replacement
Bus conversion windshield replacement costs $1,200–$4,000 installed for a two-piece set. Converted coaches from Prevost, MCI and Eagle keep the original shell glass, so the panel is sourced by the underlying coach shell and year rather than by the converter — a Marathon or Liberty conversion on a Prevost H3-45 takes the standard H3-45 windshield. Converter-added glass such as bay or entry windows is the exception and must come from the converter.

Source by shell, not by converter
Owners of high-end conversions routinely call Marathon or Liberty first and wait weeks for a quote. In almost every case the windshield is the standard panel for the underlying coach — the converter never touched the front cap. Give a glass specialist the shell make, model and year and the part is usually identifiable in minutes.
The exception is any aperture the converter cut: bay windows, entry-door glass, and occasionally an enlarged driver-side window. Those are custom and do have to come from the converter or a fabricator working from a template.

- Prevost XLII half: $900 – $1,800 installed
- MCI shell half: $800 – $1,500 installed
- Eagle or vintage shell half: $1,100 – $2,400 (limited supply)
- Full two-piece set: $1,200 – $4,000 installed
- Converter-cut bay window: $600 – $1,800
Vintage shells and glass scarcity
Eagle, Silver Eagle and older MCI shells are the hard cases. Original panels are long out of production and the supply is whatever remains in distributor inventory plus what a fabricator can build to a mold.
For those coaches, buy both halves when one breaks. Sourcing a matching second panel a year later is frequently harder and more expensive than buying the pair up front, and mismatched tint between an old and a new half is visible from the outside.
Interior work a conversion adds
Conversions put cabinetry, dash fabrication, upholstery and wiring right up against the windshield frame in a way a factory coach never does. A technician has to remove or protect that work before the panel comes out, which adds labor time and is the main reason conversion glass jobs quote higher than the same panel on a fleet coach.
Discuss trim removal explicitly before the appointment. A converter-built dash cap that has to be pulled is a different job than a factory dash, and the quote should say who is responsible for refinishing it.

Frequently Asked Questions
Who makes the windshield for a Prevost conversion?
Prevost. The converter builds the interior, not the front cap, so the windshield is the standard shell panel for that model and year and can be sourced without contacting the converter.
How much is a bus conversion windshield?
$1,200–$4,000 installed for a two-piece set, with a single Prevost H3-45 half running $1,000–$2,000.
Should I replace both halves at once?
On vintage shells, yes. Supply is limited and tint matching between an old and a new panel is visible, so buying the pair avoids a harder search later.
Why do conversions cost more to glass than fleet coaches?
Custom dash caps, cabinetry and upholstery run up to the windshield frame and must be removed or protected, adding labor beyond the panel set itself.
