Jason, I agree with Leon, you have a very sturdy fixture on the Landy, even side support at the bottom. I would firstly get combination on very level standing to determine exaxtly how much you must "drop", and if neede get a 8hole 15mm or whatever thickest drop plate, so tha tyou have at least 4 decent high tensile bolts to attach the drop plate, and tne same bolts to attach tow ball.
It is diffecult to judge from the pics, but I would say you need to drop at least 100mm. If you really want to spend some money, have the van fitted with spacers and upgraded axle to lift the van, and if still fitted with 13" wheels, go for 14".
Why not simply replace the bottom swivel hitch with your or a standard towball hitch? (Last photo shows it very clearly) There is lots of strength and stability there on the bottom set of bolt holes.Do you use the bottom swivel drop pin hitch? It does not look as if it has been used for ages. Do not lower the hitch with another drop plate!
A std tow ball should give you about 50mm drop, if you dont need the swivel hitch, try one before buying a drop plate however, having said that, looking at your last photo, you have good ground clearance which might be lost using a drop plate.
Leon ons gebruik die ball and swivels kombinasies by die werk vir verskillende tipe sleepwaens, die dubbel tipe is so 50mm langer as die standaard ball haak.
Leon, as mens mooi kyk na Jason se fotos, dink ek jy is reg, 50mm sak gaan dalk nie voldoende wees vir "nose down" nie. Drop plate is gaan dalk tog nodig wees hy het goeie grond vry hoogte.
Johann, presies wat ek in my plasing genoem het, kyk na die hele plasing, met my voorstelle ten opsigte van hegboute ens.
Jason, before you hurry to buy 6 hole, rather look if you can hook up nad measure as it is, rather go then for 8 hole, and stick to the 4 HOLDING bolts to the existing plate. I don't think 6 hole is going to be enough. You will only be sure if you hook up and measure. Rather go to towbar fitment centre, drop plates will normally be cheaper there.
Jason, instead of doing complete hook-up on very level surface like driveway or so, let van stand on the jockey wheel, hence giving you chance to lower until you see it is level or slightly nose down, then you measure to inside of the cup of the towhook of the van, and next measurement to the top of tow ball on vehicle, (if standard tow ball was fastened), giving you the correct figures of drop plate you will need.
I dont think your vehicle is going to drop more than 2cm when you hook up the van, so if you work on actual level measurements, van will be only a wee bit nose down on vehicle rear side drop.
Jayson, dit lyk vir my dit gaan werk, Jou wa loop mooi in lyn met die Landy se dak, en jy het die krag om daai wa te trek.
Keep us updated on your trips with that rig.
the line up and combo look good.
"Just a comment about the "open holes' at the top of the drop plate. My intention was to use 4bolts to attach the drop plate, but the holes of the drop plate and the landies fitted drop plate do not align. I didn't want to use the first set of holes as this might lower the drop plate too far and therefore the vans nose too."
For what it is worth, I dont see any problem with the setup as it is now, since your Landy's dropplate is properly supported. Your bolts holding the bottom dropplate is the weakest link, as long as they are of good quality steel, you should not have any issues.
Jayson, my dropplate se gate het ook nie opgelyn nie. Ek het dit ingevat en gevra dat gate toe gemaak moet word en dat hulle vir my nuwes moet boor. Nou gebruik ek al 4.
Jayson, looks much, much better!!!!! I would also seriously advise as Kurt above, get the holes custom drilled at engineering firm, and if needed some holes closed. It will give you tremendous feel of security if you know you have the drop plate secured with 4 decent bolts.
It is for your own and your family's good, and if there is a need to sell the Landy some day, surely new owner will appreciate it.
