Stering Gear box question

[Byron-521]

I would like to know if a gear box from a 1978 620 Datsun fits in a 1971 521 Datsun?

Yes.

 

Unless yours is bad, no need. They're both 4.375.

Yes.

Yours only has one gear?  Weird.

He meant differential, did he not?

 

 

If not, the answer is yes, kind of. Well covered.

If your talking about the 5 speed, it will not without shift lever location, transmission mount, and driveline modifications, it's not a bolt in.

What wayno said.

 

620 (4 or 5 speeds after '73) will bolt to the engine but be about 5.5" too long. The rear transmission mount will also be in another position and not line up.

Mines is a 4 speed trans, & truck tends to go to the left when driving. I figure it's the gear box taking a dump, & a friend has a 78 Datsun truck & said he will give me his but we don't know if it will work on mine 521?

The steering wheel gear box**

[datzenmike]

Bad front alignment makes it veer to the side. If your 4 speed is working leave it alone and fix the alignment. Bad alignment can be caused by an adjustment being out, but on an old truck it's much more likely that some steering parts are worn out and need replacing.

 

A worn box will have lots of side to side movement without much steering effect.

Wow. We were all wrong. Be specific to help others to have a better chance of helping you/answering your question.

Shifting gears makes you go sideways. Maybe it's looking at tail while driving!
