Holley assembly line set of six pack carbs. 4391 center manual trans, 4393 and 4394 outboards. All carbs are within 30 days of each other. I went through them replacing gaskets, accelerator pump diaphragm etc. Both secondary diaphragms hold vacuum. You can likely use these as is or send out for professional restoration. Asking 2100 plus shipping for the set.
