What do you need to put a 5 speed manual transmission out of 86 f-150 with 300 in bronco auto 351w?

Swapping a 5-speed manual transmission from an '86 F-150 (likely a T5) into a '78-'79 Bronco with a 351W automatic requires more than just bolting it in. It's a significant project. Here's a breakdown of what you'll need:

1. Transmission & Related Components:

* 5-speed manual transmission (T5): Ensure it's from a compatible year F-150 and ideally, one with a similar engine (e.g., 302). The bellhousing and input shaft might be different depending on the exact year and engine combination.

* Clutch assembly: This includes the clutch disc, pressure plate, throw-out bearing, and pilot bearing. The clutch assembly must be compatible with both the transmission and the 351W engine's flywheel.

* Flywheel: The automatic transmission likely used a flexplate; you'll need a flywheel that's compatible with the 351W and the clutch assembly. It might require machining or balancing to be certain.

* Clutch linkage or hydraulics: You'll need a clutch pedal assembly (if it's not already present), clutch master cylinder, clutch slave cylinder, and all the necessary lines and hardware. The Bronco's existing setup needs adaptation.

* Bellhousing: The bellhousing from the F-150 *might* work; however it will need to be checked very carefully and might need replacing with a bellhousing that is compatible with the 351W.

* Driveshaft: The driveshaft length will almost certainly be incorrect, requiring a custom-made or shortened driveshaft. This is a critical safety component that *must* be correct. Incorrect length can result in damage or failure of the transmission, differential or transfer case (if present).

* Shifter linkage and components: You will have to adapt the shifter to the Bronco's interior and potentially modify the transmission tunnel.

2. Engine Modifications (Possibly):

* Possible Engine Modification: The 351W might require a different starter, as automatic and manual starters may have slightly different positions/mountings.

3. Vehicle Modifications:

* Clutch pedal assembly: The Bronco needs a clutch pedal and related linkage. You'll have to source and install this.

* Transmission tunnel modification: You might need to modify the transmission tunnel to accommodate the 5-speed's larger dimensions compared to the automatic.

* Wiring: Some wiring changes might be necessary for the reverse lights, neutral safety switch (for starting), and perhaps speedometer operation (speed sensor might be different).

* Crossmember: The transmission crossmember will likely need to be modified or replaced to properly support the 5-speed.

4. Tools & Expertise:

* Specialized tools: You'll need various transmission tools, torque wrenches, and potentially a press for installing bearings.

* Mechanical knowledge: This swap requires significant mechanical expertise. If you're not comfortable working on transmissions and drivelines, it's best to seek professional assistance.

5. Parts Sourcing:

* Finding all the necessary parts, especially a bellhousing that's a good fit for both transmission and engine, might take time and research. Online forums dedicated to classic Broncos or Ford trucks will be helpful.

In short: This isn't a straightforward bolt-on swap. It's a major undertaking requiring mechanical skill, specialized tools, and a good understanding of automotive drivetrains. You'll spend considerable time and money on parts, modifications, and potentially professional assistance. Thoroughly research the specific compatibility of the components before purchasing anything.
