The right transmission inspection plate depends on the vehicle and transmission: Ford C6 pickup owners should match the year and truck model, while many GM owners need a 62 mm bell housing inspection cover. The Ford listings below target specific F-100, F-150, and F-250 applications. For GM vehicles, the GM Genuine Parts cover is an OE-specification option, while the other listings describe replacement covers with broad fitment claims. Confirm the exact part number, dimensions, and vehicle fitment before ordering.

Ford F-250 C6 Inspection Plate
This replacement automatic transmission inspection plate is listed for 1968–1976 Ford F-250 pickup trucks with a C6 transmission and big-block engine. It is the most directly targeted choice in this group for an owner restoring or repairing that specific truck configuration.
Best for: Buyers whose F-250 year, engine, and C6 transmission match the listing. It was selected because the application is clearly tied to a specific classic Ford truck range.
Check before ordering: The listing directs shoppers to its description for specific fitments. Confirm the engine and transmission details rather than relying on model year alone.
Ford F-150 C6 Inspection Plate
This plate is described as a replacement for 1975–1976 Ford F-150 pickup trucks with a C6 automatic transmission and big-block engine. Its narrower year range makes it a more specific option than a general-purpose transmission cover listing.
Best for: Owners of a 1975 or 1976 F-150 who have verified the C6 and big-block configuration. It was selected for its stated application to this truck model.
Check before ordering: The product information says to consult the description for specific fitments. Avoid assuming that every F-150 from those years uses this plate.
Ford F-100 C6 Inspection Plate
This replacement plate is listed for 1968–1976 Ford F-100 pickup trucks with a C6 transmission and big-block engine. The stated fitment makes it the Ford option to investigate when the truck is an F-100 rather than an F-150 or F-250.
Best for: F-100 owners matching the listed years and drivetrain description. It was selected because the listing identifies the specific truck series and C6 application.
Check before ordering: Specific fitments are deferred to the product description. Verify the truck’s configuration and compare the replacement with the original plate when possible.
GM Genuine Parts 24205900 Cover
GM Genuine Parts identifies this 24205900 transmission bell housing inspection cover as a recommended replacement for a GM vehicle’s original factory component. The listing says it is manufactured to GM OE specifications for fit, form, and function.
Best for: GM owners who want a part described as meeting GM OE specifications. It was selected as the manufacturer-branded option among the listed GM covers.
Check before ordering: The supplied feature information does not provide a full vehicle fitment list. Verify the part number and 62 mm cover requirement for the specific vehicle.
Ziyuan 62 mm GM Inspection Cover
This Ziyuan cover lists replacement part number 24205900 and describes a 62 mm bell housing fitment for 2002–2017 GM vehicles. Its features specify stainless steel construction and three tangs, and mention compatibility with 6L80 and similar GM transmissions.
Best for: Buyers who have confirmed that their vehicle uses a 62 mm cover and whose part number and transmission match the listing. It was selected for its stated dimensions and construction details.
Check before ordering: The application list spans numerous vehicles and years, so make a vehicle-specific fitment check. The listed “similar” transmissions should not be treated as confirmed fitment without verification.
Buying Guide: How To Choose A Transmission Inspection Plate
Does the vehicle use a Ford C6 plate or a GM bell housing cover?
Start with the vehicle make, model, year, engine, and transmission. The three Ford listings are described for specific F-series trucks using a C6 automatic transmission and big-block engine. The GM options identify bell housing covers by part number and, for some listings, by 62 mm size. These are not interchangeable categories.
What should you verify before buying?
- Vehicle details: Match the year and exact truck or vehicle model to the listing.
- Transmission and engine: Confirm the transmission type and engine configuration, especially for the Ford C6 plates.
- Part number: For GM applications, check whether 24205900 or another listed number matches the original part.
- Dimensions and design: Confirm the 62 mm size and tang configuration where applicable.
- Listing fitment: Broad vehicle lists can include multiple transmission setups. Verify the exact application instead of relying on a nameplate alone.
Should you choose an OE-spec or aftermarket listing?
The GM Genuine Parts listing states that the cover is made to GM OE specifications, but the supplied details do not give a complete fitment list. The aftermarket GM listings provide more application or construction details, but their broad compatibility claims still require confirmation. Choose based on verified fitment and the information available for your vehicle, not on brand wording alone.
Frequently Asked Questions

No. Plates and covers vary by vehicle, transmission, dimensions, and design. Match the part to the exact application.
Is 24205900 the same as a 62 mm cover?
The Ziyuan listing identifies 24205900 as the replacement part number and describes a 62 mm cover. Confirm that both details match the vehicle’s required part.
Will a Ford C6 plate fit every F-series truck from the listed years?
The listings specify different F-100, F-150, and F-250 applications, along with a C6 and big-block engine. Verify the exact truck and drivetrain before ordering.
What if the vehicle fitment information conflicts?
Use the original part number, dimensions, and transmission identification to investigate the correct fitment. If the listing remains unclear, confirm the application with a parts professional before purchase.
