I am looking for the Chrysler part numbers for a hand throttle to fit on my '92 truck (or even pre '92 trucks). I remember seeing some posts about this subject when the older version of this web site was being used. However, a search doesn't turn anything up that is useful. The local Chrysler dealer doesn't show anything either. I would like to be able to set my truck up for variable high idle speeds since it is getting cold out. If this fails, I will go with a generic hand throttle, but I thought I would try to go for factory parts first. Thanks for the help.
