seat belt question

[datsunrides]

It appears my late 65'-early 66' 520 did not come with seat belts, at least that I can tell. There are no anchor points in the back of the cab like a 521. Sound right?

they had lap belts i think. did you check the floor?

There should be four (4) 3/8" holes on the floor of the cab, approx 7.75" from the rear bulkhead. These are the anchor points for the lap belts.

Nope, no hole in the floor or the tunnel, other than the rear cab mount bolt and the drain plug.

Does not sound right for a USA-spec 520.

Pictures in my post here-- http://community.ratsun.net/topic/54469-new-seatbelts-for-the-520/  USA-spec '65+ truck should have them.  If not, check for anchors under the truck... someone may have welded them over during floor pan repairs.

Bolt holes at door sides are in the side of the cab near floor and I think are fine thread

So check the pics. This is a bare sandblasted cab with original metal, no patches.

 

 

 

I don't see the bolt holes.

You can't see from those pics. Should be in the sides near the floor.

These are picturs from a 1970 521. 

Outside seat belt.  The seat belt bolt actually is not in the floor, it goes into the side of the cab.

Center seat belt.

the bolts holding the seat belt brackets to the floor, and side of cab are 7/16-20 thread.]

This is what I'm getting at. There are no holes. I have a 521 also and know where those are, as stated in the 1st post. There is nothing in those locations on my 520. How about this, did 320's have seat belts from the factory?

All passenger vehicles (except buses) legally sold in the US were required to be fitted started January 1, 1968.  Most companies had already started complying before, and as I commented in a previous post, believe your '66 should have had them if it was a US-spec truck.  However, maybe not.  Your original question is really answered... clearly you don't have them.  However, is there an underlying question you haven't asked yet?  Are you just curious about it (as I am)? Or are you trying to determine if this is a US-spec cab?  Or???

More from the legal aspect. I don't plan to roll without belts, but if I did, I need to make sure it's "legal". The biggest issue is I know you can't just bolt belts to the floor pan. It'll rip the bolts out in an accident. I know I can reinforce the anchor point, but not sure of the best point. The other issue is it's all painted so I don't want to cut it up or weld to the cab at this point.

Pre-1968 is not legally required to have seat belts.

Speedway and others sell seatbelt anchor plates.  The purpose of the plates is to distribute the load across a larger area and to soften the contact (by rolling the plate round on the sides) so it doesn't have a sharp edge to facilitate tear-through.  I would try to mimic the factory points, as the cabs are likely already much stronger there.
