Galvanized chassis options for NAS with 300 Tdi

NAS300tdi

New member
My ’95 NAS Defender 90 is due for a new galvanized chassis. The original V8 was removed and a 300 Tdi is paired with the R380 . There are a few replacement chassis options for the 300 Tdi with location of the fuel tank being a difference. Beside the motor mounts, are there other differences between a NAS 90 chassis and a 300 Tdi ROW chassis?



Many thanks,

If I remember correctly, A friend of mine had Richards make the 300tdi front with the NAS rear fuel tank.

Puma chassis have rear tanks, very similar fuel tank. I've sold 2 rear tank 300tdi Marsland chassis(no offfense to Richards but they're not even comparable) for NAS 90s.

I believe 98 is the year 300s switched to rear tanks, but Im not near a parts book at the moment

There were late-run 300s with the rear tank mount. Basically just a TD5 tank with a drop-in sender/pick up just without an integral fuel pump. Td5 rear tank mounts look different than NAS mounts but the mount the same tank essentially. Unless I’m mistaken the only difference is the rollover valves/evap vents on top.

Really you can make any 90 chassis work, but it will be much easier if you just order a 2006-spec one from a supplier.

We both got Richards chassis, mines a 110 200tdi and neither of use had any complaints. Not sure what makes the Marsland so much better?

OEM vs aftermarket hand welded. Far more issues with Richards than Marsland in our experience. If you look at the two next to each other it's very apparent

My Richards chassis is structurally fine but has some worksmanship issues. For one, the doors never aligned with the relativee precision of the factory frame. I suspect this has to do with the bulkhead mounts. Another big issue is the front bumper. There are two tubes on each side where the bumper bolts pass through the frame. On one side, one of the tubes is not straight, causing the holes on the factory captive plate to be about 1/8" off on one side, enough to make it completely non-functional. To fit my bumper, I had to manufacture my own captive plate with a wider hole spacing.

Now that I'm doing my own welding, I appreciate just how difficult it is to get perfectly square alignment on everything but these guys should be pros and I expected better. The doors issue is particularly annoying because my truck leaks like a sieve and no amount of door/bulkhead/tub maneuvering, hinge replacement, door seal replacement, etc., etc. will fix it. I've literally spent whole weekends trying to get the doors to seal and shut correctly.

If I ever do this again, I will look for a Marsland chassis.
