JumboFett Posted September 19, 2022 Report Share Posted September 19, 2022 Hey guys! Does anyone have input on which modern-style retractable seatbelts (shoulder and lap belt combo with a singular latch) work for a ‘74 620? Either aftermarket or taken from a different make/model is fine. Thank you 🙏 Quote Link to comment
datzenmike Posted September 20, 2022 Report Share Posted September 20, 2022 King cabs mount the center two anchors differently so get a regular cab belt set from '76 and on. These use a single latch shoulder/lap belt. I don't think the mounting point for the retractor on the floor at the base of the B pillar will match anything on the '74. The top one might fit an existing threaded hole. 1 Quote Link to comment

In related news, I’m surprised almost daily that someone with the means and the know how hasn’t capitalized on the gaping aftermarket void present in the Datsun 620 community. The Chevy guy in me is thoroughly bewildered! Quote Link to comment
FrankRizzo Posted September 20, 2022 Report Share Posted September 20, 2022 I custom ordered red belts with aviation buckles from seatbeltplanet.com. They were very helpful.... 1 1 Quote Link to comment

Why do I think the Datsun truck aftermarket is not a sound business model? Because Datsun truck owners are notoriously CHEAP BASTARDS. No offense guys. 2 2 Quote Link to comment
datzenmike Posted September 20, 2022 Report Share Posted September 20, 2022 None taken. Copper wire was invented by two Datsun truck owners fighting over a penny. S' true. 2 2 Quote Link to comment

I, for one, take great offense, as I have been willing to spend money like a drunken sailor in service of my obsession and mission objective!! 😂 I literally just got off the phone with Auburn Gear asking if they made diffs outside of their catalog, specifically those for the H190 rear end. Apparently they used to broker diffs for a Japanese manufacturer but they stopped years ago. I implored them to explore the HUGE Japanese classic market that has sprung up in the last decade; to even start Datsun forum accounts to research market interest and to see for themselves that they could corner the Datsun LSD market with minimal R&D! They showed interest in the prospect, but I’d be surprised if they follow through. I took a similar tact with Flaming River. I tell you what, if I could figure out a R&P solution using Flaming River products my efforts will be plastered all over this site, and we can finally lay to rest the mystery of the gahtdamn rack & pinion solution. 2 Quote Link to comment
datzenmike Posted September 21, 2022 Report Share Posted September 21, 2022 Datsun trucks don't really have traction problems to need an LSD. They are a lot of money for something along for the ride. Over steer is also a lot easier to recover from with an open differential. 1 Quote Link to comment

He really knew his shit and hooked it up. Its been a while so I dont remember all the details... I used similar for my 521 - one detail I didn't anticipate was orientation of the fixed shoulder mount, piece below. It's bent at angle so only mounts one way - mounted to 'wall' of cab would have been fine, but mounted to floor (behind seat) caused a half twist in belt. Difference between perfect install and irritating flaw. Seat Belt Planet can sew custom, but it's tricky to plan how belts lay when installed without testing. Quote Link to comment
iceman510 Posted September 28, 2022 Report Share Posted September 28, 2022 They have those 90 degree angle mounting brackets that can bolt to the floor and then change the belt end to a vertical orientation. I used them for the inside lap buckle position on my 510.

Would something like that work in your situation? Quote Link to comment
