1973 Ford Bronco (First Generation) — Front Suspension Bush Identification
Vehicle & Part Overview
Vehicle: 1973 Ford Bronco — First Generation (1966–1977)
Component: Front suspension bush (specific location to be confirmed)
Setup: Stock twin I-beam front suspension
The first generation Bronco uses a twin I-beam front suspension, and suppliers frequently list bush parts by different reference points — the beam pivot, the radius arm, or individual steering components. This is a primary cause of part number discrepancies across suppliers.
Why Three Suppliers Give Three Different Part Numbers
Part number mismatches on classic car suspension bushes typically come down to:
- Superseded numbers — the original factory number, a later updated number, and a pattern parts number can all refer to the same bush but look completely different on paper
- Internal catalogue numbers — some suppliers use their own numbering system rather than the original manufacturer reference
- Position-based listings — many classic vehicles used the same bush in multiple suspension locations, but suppliers sometimes list them separately by position, creating the appearance of different parts
Identifying the Correct Bush
The most reliable method is to work from physical dimensions rather than part numbers. Measure the following from the bush you are replacing:
- Outer diameter
- Inner diameter
- Length
With these three measurements, most suppliers can cross-reference to the correct part regardless of which catalogue number they are using. Also confirm:
- Which specific joint or arm the bush sits in (radius arm, axle pivot, or other)
- Whether the suspension is stock twin I-beam or a modified setup
Sourcing Recommendations
The following specialists are recommended for first generation Bronco suspension components:
- Dennis Carpenter Ford Restoration Parts — strong coverage of early Bronco and Ford truck components
- Bronco Corral — particularly useful for suspension-specific parts
- Classic Industries — carries a broad range of early Bronco parts
Fitment Notes
Once physical dimensions are confirmed, cross-reference your three part numbers against each supplier's listings. It is possible that all three numbers describe the same bush, that only one is correct for your specific suspension point, or that none of them are correct. Dimensions are the definitive check.
- Do not assume the most commonly listed part number is correct — superseded and pattern numbers are widespread on first generation Bronco parts
- Confirm whether your Bronco retains the stock twin I-beam setup before ordering, as modified suspensions may require entirely different bush specifications
