Aftermarket Lower Control Arm problems

[TooMany2count]

I'm helping a friend w/his 95 Chevy 3500 truck, it came w/drop lower A-arms. He has no idea who's they are but needs to get the bushing for them. So can someone point me in the right direction by telling me some of the manufactors who make them & maybe a link to their website. The only ones that I have found that were even close were DJM Suspension Parts, but they say they don't make anything for that year 3500 series truck.

thanks....joe
