Year tells

Fuel doors and vertical rear markers are unique to 1977. E H

Fuel filler doors replace external caps, and rear markers mount vertically. E H
Heavy-duty 9-inch rear housing. E H
The passenger seat and padded dash became options. E H
14.4-gal plastic tank and 8-gal auxiliary. E C

Reading the VIN

Format: series (U13 roadster, U14 pickup, U15 wagon), engine letter, plant letter (H Lorain, L Michigan Truck, R San Jose, S Allen Park), then the serial number. Example: U15SLAE0010. L
1977 serial range: 00,001–Z20,000 (as printed by LMC). L

1977 Ford Bronco options, packages & interior

Sport, Ranger and Special Decor Group. F77 E
Special Decor stripes came in white, yellow or black per forum owners. CM

Interior

Most early Broncos had simple low-back front bucket seats and a basic rear bench, and utility U14 half-cabs often had a front bench. Wild Horses, a parts vendor, describes the factory seats as flat and unsupportive by modern standards. WHS
Interior kits, seats and dash parts for a 1977 are covered on our early Bronco parts page. WHP

1977 Ford Bronco colors

Hagerty counts 18 paint colors for 1977. H

Buying a 1977 Ford Bronco: inspection checklist

Body: panel by panel

Rocker panels: a known rust area that often carries into the floor pans. SD
Floor pans: lift the carpet and check the seat mounts and footwells. SD H
Rear quarters and inner fenders: anywhere mud, water and salt collect. SD H
Inner door frames at the hinges, the firewall and inner fenders. SD
Tailgate bottom and roof seams: the panels most often named in buyer guides, though the sources cited here don't single them out. H
Tap suspect metal with a pick (a ping is good, a thud is rust) and use a magnet to find filler. SD

Frame

Steering-box mount area on the frame: check for cracks, one of the most common failures. KC
From the rear bump stops back to the rear body mounts: rust collects under the rail. KC
Under the rear shock mounts: probe with a screwdriver. KC
Front and rear frame horns: check for bends, cracks or rust. KC
Body mount holes, especially under the pads. KC
Welds at suspension, engine mounts and crossmembers, and the drain holes. Rust can work from inside out, so a borescope helps. KE

VIN, data plate and numbers-matching

Match the frame stamp (passenger-side rail, below and behind the starter) to the plate and the title. O
Decode the VIN: series U13/U14/U15, then the engine letter, plant letter and serial. A 1977 serial should fall in 00,001–Z20,000 (as printed by LMC) (LMC). L
The engine letter must match what's under the hood if the seller claims an original engine (G = 302). L
Door tags can be faked ('repro' tags have been sold for years). A Marti Report lists the factory options, paint, axle and build dates. M

Mechanical

Sixes and the 289/302 are simple and cheap to rebuild. Rebuilt 3-speed Toploaders were about $600 in 2021. H
Check the Dana 20 and its Bronco-specific front mount, and confirm the front axle type, which a seller may not know. H

1977 Ford Bronco upgrades & swaps

Front disc brake conversion (factory discs already fitted from 1976). SX CB
Power steering conversion (factory option from 1973). SX CB
2.5-in lift: the 'sweet spot' for 31–33-in tires. Replace all bushings (track bar, radius arm, C-bushings) at the same time. SX CB
EFI conversion on the original V8, or a Coyote 5.0 swap. Coyote installs usually need a 2–3-in body lift, a low-profile pan and a moved column, and most use a 6R80 automatic. SX TD TO
With big power: 31-spline 9-inch axles, an HD Dana 20 output or Atlas case. TO
Floor shift conversion off the column 3-speed, and a J-shifter upgrade, are owner favorites. CB

Roll bars were never a factory option on early Broncos. A family-style cage protects rear-seat passengers and gives a mount for the rear belts. WHR

Restoring a 1977 Ford Bronco

Start with the frame: check the steering-box mount for cracks, the rails from the rear bump stops to the body mounts, and under the body-mount pads. KC
Rust can work from the inside out, so check the welds and drain holes with a borescope. KE
Body: the rockers often rot into the floor pans, and the inner door frames, firewall and inner fenders are next. Complete steel body tub kits are sold for 1966–77 trucks. SD WHB
Do one area at a time, buy complete kits rather than piecemeal parts, and plan upgrades such as discs and power steering into the restoration. CB
