Most accessable to me were Volvos- I made new brake lines, new spring & shock mounts, and flange adapters. For the drag link I cut the stock volvo link and slid it over the Cruiser link.
Price however seems to have gone way up. Five years ago you could get into a pair of portals for about $2000. Anything now days, especially new and custom will be $$$$. Personally if I was going portal again I would fabricate some hum9s for ease of parts.
