I need a caster adjustment kit for a 1981 280zx 2+2 I know a few companies made them a couple of years back but I cannot find one now. Can anyone help?

When you say 'caster' do you mean 'camber'? If you mean camber adjustment, kits are available from MSA. For caster adjustment you would need adjustable tension rods and I don't know who makes those for a ZX.

Adjustable tension rods (sometimes called "pillow tension rods") for the Z can be found on eBay and Yahoo Japan, but I'm not sure if they will work on the ZX. I vaguely remember someone here making their own by cutting additional threads on the existing rod, but it may have been on another site.

it is for caster adjustment that I need. I thought about cutting more threads on the exisitng rods but I am not sure that is possible. Still would like to get the caster adjustment kits. I know they made them up unitl a couple of years ago but I cannot find any now.
