Hello....Sort of newbie here, but mechanically inclined. I'm rebuilding the carbs in by 99 Challenger 1800 with 787's. Ordered carb gaskets (for where the carbs mount on the manifold) and they are way thinner than the thick ones that are on there. The thick ones are blue. Can I use the thinner ones, or was I sent the wrong ones? I was told that the thick ones are discontinued. Is that true? If I can use the thinner ones, will the carb bolts be too long? Thanks for the replies!
