i think thats an splitty beam at acvw.net , but give them a shout, i might be wrong...
for the front the best way to go is it a narrowed adjustable beam, with droppped spindles, and either early beetle gr-2s or empi has a gas shock for the for early beetles that work well. your wheel choice will dictate how narrow you will need to go on your beam
how low you want to go on the rear will dictate what you need to buy...
if only a couple inches lower, you wont need anything, just adjusting the splines,
if you go any lower than that, you can use notched spring plates for extra clearance before you bottom out..
and for slammed vans the easiest way to lower them is with \"horseshoe\" plates which bolt on and lower your van about 3 inches more, without screwing with your camber too much...
in any case while your in there replace all the bushings, seals, tie rods, shocks, flex lines (you may need longer flex lines with the horseshoe plates) and any other wear part.
another fun thing to do while your in there is to install 7/8\" swaybars all around, you wouldnt believe how well your van will handle and ride after all those mods... and of course acvw.net will hook ya up with all that stuff
