They actually list all Chevy 6 cylinder engines from the 40s onwards The unit that works in the car distributor also works in the truck distributor (they should have listed them in both places).
In the past year or two, they have listed 6v positive and negative ground units.
How different are the Chevy & GMC distributors between 1941 and 1962?
Nonetheless, there is a Pertronix unit for greg63's 283.
Almost evceryone who has posted opinions about Pertronix units has had positive experiences. The only problem that has been posted is that it seems some units might have gone bad due to out-of-range voltage being supplied to a unit. Pertronix will recommend a few types of Zener Diodes to protect the units; but, they do not sell any of the diodes, nor have I been able to find anyone that sells them retail or in numbers less than 100-1000 units.
