Sorry like I said first time poster. So is there anyway to fix slot 171?

Those are the ones that I downloaded, I tried again and it gave me the same error. I'm deleting the old buildcraft files and just replacing them with the new? Is there something else I have to do?

I did and it says, java.lang.IllegalArgumentException: Slot 171 is already occupied by buildcraft.builders.BlockPathMarker@74e175f3 when adding buildcraft.factory.BlockPlainPipe@7e06e077 at pb.<init>(Block.java:251) at buildcraft.factory.BlockPlainPipe.<init>(BlockPlainPipe.java:30) at BuildCraftFactory.initialize(BuildCraftFactory.java:96) at mod_BuildCraftFactory.modsLoaded(mod_BuildCraftFactory.java:36) at cpw.mods.fml.common.modloader.ModLoaderModContainer.postInit(ModLoaderModContainer.java:362) at cpw.mods.fml.common.Loader.postModInit(Loader.java:290) at cpw.mods.fml.common.Loader.initializeMods(Loader.java:629) at cpw.mods.fml.client.FMLClientHandler.onLoadComplete(FMLClientHandler.java:223) at net.minecraft.client.Minecraft.a(Minecraft.java:429) at net.minecraft.client.Minecraft.run(Minecraft.java:738) at java.lang.Thread.run(Unknown Source) --- END ERROR REPORT defdfd3d ----------

Hey, first time poster so sorry if I did this in the wrong place. I have a tekkit classic map that I have been playing in on my server forever, I recently put it into my single player tekkit classic because of the server having a map reset. I started messing around with automatic builders and discovered that blueprints aren't in tekkit classic. So I put my map in Technic ssp to try to get blueprints and all of my items disappeared. Luckily I had made a back-up of the world. So my question is, Is there a way to get the new buildcraft version in my tekkit classic map without completely destroying it?
