I'm sure this has been covered countless times in this forum but I'm considering it for my street strip '79 D100. What year range B van do the LCAs need to be from and is it 1/2 or 3/4 ton? I just read about this swap in the unlawful forum so forgive my ignorance. I plan to use moroso trick drag springs with it also. If I need anything else feel free to fill me in. Also does anyone know if someone makes tubluar UCAs for my truck?
