However, you need to confirm the following:
* Transmission Type: Are both trucks equipped with the same type of transmission (e.g., SM465, Saginaw 3-speed, Powerglide, etc.)? This is the most crucial factor. Different transmissions are not interchangeable.
* Gear Ratio: While the transmission type might be the same, the gear ratios within the transmission could differ. This will affect performance and speedometer accuracy.
* Bolt Pattern: While unlikely to be significantly different between consecutive years, double-check the bolt pattern on the transmission's output shaft where it mates with the driveshaft. A slight difference could cause problems.
* Bellhousing: The bellhousing, which connects the transmission to the engine, must match the engine in both trucks. A '67 and '68 bellhousing might be interchangeable, but it's essential to confirm compatibility with the specific engine.
In short, while it's *probable* they'll interchange, you absolutely need to verify the specific transmission type and other details before assuming compatibility. Consulting a parts catalog or a Chevy truck parts specialist is highly recommended.
