I've been in talks with Le Tech USA, ORC.de, Wolfgang, killer axles and gfg, etc. all North of $20K. For now I'm saving $20k by placing a custom spring lift/ Body lift and adding 2" spacers to each wheel. Same look minus the portals. There is a company out of the Philippines that sells a bolt on portal for G wagons at $20k USD. They've had complaints about cheap metals being used which have broken down for clients. They've assured me they have the problem solved. When/if portal axles get to the $10k range I'll be the first in line. It's just hard for me to Justify the cost when I paid $19,900 for my 2003 G500.
