MantisX620 Posted February 5, 2016 Report Share Posted February 5, 2016 Does anyone know what the bracket is for in the center of the back wall of the cab of a 620? I want to remove this to make room for a subwoofer box im making. It would easier to remove it than to build a box around it. It looks to be just spot welded on. Thanks MantisX Quote Link to comment
datzenmike Posted February 5, 2016 Report Share Posted February 5, 2016 It's for holding the bottle jack crank handle. Quote Link to comment
MantisX620 Posted February 5, 2016 Author Report Share Posted February 5, 2016 Hey Mike. Not those little tabs that hold the long handle, but the bigger bracket that sits on the transmission hump and the center of the back wall. It kind of has a triangle shape. I tried taking a pic but its too dark. Quote Link to comment
datzenmike Posted February 5, 2016 Report Share Posted February 5, 2016 I don't know... is it a King Cab? My KC had some sort of support bracket on the outer under side, It was a '78 but the cab I had to swap for an earlier one. My '78 FSM shows it but it's not a separate part and spot welded in. The KC has quite an unsupported overhang to the rear. Just extra bracing??? Quote Link to comment
MantisX620 Posted February 5, 2016 Author Report Share Posted February 5, 2016 Mine is a longbed. Heres a pic I was able to find on the net. Its still not great, but see that long piece thats coming up off the trans hump onto the back wall? Quote Link to comment
datzenmike Posted February 5, 2016 Report Share Posted February 5, 2016 Regular cab then. Yup, my '78 FSM shows it but the cab in my '78 was swapped. It didn't have that but did have some kind of outside support to the frame on it. The cab I replaced the '78's with was either a '76 or '77 (I think) King Cab. It's just support I imagine. 2 Quote Link to comment

MantisX620 Posted February 6, 2016 Author Report Share Posted February 6, 2016 Thanks guys. Ill take a closer look and see if its something I can lose without headaches later. Quote Link to comment
cruznude Posted February 9, 2016 Report Share Posted February 9, 2016 I've owned datsun trucks for 39 years now, and honestly I have never seen those support braces ever in any of the trucks I have owned or at scrap yards. I'm confused. 1 Quote Link to comment
5t341tH Posted February 11, 2016 Report Share Posted February 11, 2016 mine has it too Quote Link to comment
MantisX620 Posted February 12, 2016 Author Report Share Posted February 12, 2016 Very odd that this only seems to be in certain trucks. Is there an accessory that came with these trucks that mightve utilized it? I see the spot welds on it and with a little time, im sure I could remove it. Visually, it doesnt seem to be doing anything really important. MantisX Quote Link to comment
datzenmike Posted February 12, 2016 Report Share Posted February 12, 2016 Then why remove it? It should be out of sight behind the panel. Quote Link to comment

]2eDeYe Posted February 12, 2016 Report Share Posted February 12, 2016 It's likely it was added to the later model trucks to reinforce the cab for safety reasons. Remember 78 was around the time covairs and pintos were blowing up :lol: 1 Quote Link to comment
sebpv Posted February 13, 2016 Report Share Posted February 13, 2016 Its on my '73 std cab too, js... 1 Quote Link to comment
cruznude Posted February 17, 2016 Report Share Posted February 17, 2016 I guess that bracket was there so you wouldn't ignite while the truck was exploding.lol. Its there for whatever reasons and we're not nissan/datsun designers so go figure. Quote Link to comment
MantisX620 Posted May 23, 2016 Author Report Share Posted May 23, 2016 For anyone who cares, I removed the bracket a weekend ago by drilling the spot welds. No adverse effects so far. Now my box fits correctly too. MantisX Quote Link to comment
]2eDeYe Posted May 23, 2016 Report Share Posted May 23, 2016 I realized neither my 77 nor my 78 have this bracket, weird. Quote Link to comment
2wheel-lee Posted May 26, 2016 Report Share Posted May 26, 2016 Unless you're closer to 5' than 6' I can't imagine that you'd have much space for a fully enclosed enclosure in a standard cab 620. I'm guessing at most, you can fit four 8"s or two 10"s. Back in the day, we made enclosures that sealed against the back wall and floor of the cab of minitrucks, so we could get more enclosure volume and space for larger magnets. This way, we didn't need to worry about most brackets that protruded from the wall. 1 Quote Link to comment
MantisX620 Posted May 26, 2016 Author Report Share Posted May 26, 2016 Im actually using some 6.5" subwoofers. I plan to run 6 of them in a built ported box. I have 2 6.5s back there now in a 5 1/4 deep ported box on about 800 watts. Sounds great. I have people guess what they think is back there after they hear them and Ive gotten, one 15, two 12's four 8's etc. LOL I do like the idea of a box sealing to the cab. Did you have much rattle issues on the back wall when you did that? MantisX Quote Link to comment
5t341tH Posted June 7, 2016 Report Share Posted June 7, 2016 Pics? I'm interested in how the box looks behind there Quote Link to comment
