Tekkit Classic Buildcraft Help

[ilikeslushis22]

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?

Download it and replace the mod in the mods folder

I did and it says,

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?

its something wrong the slot 171 >.>

If you put the title "Tekkit Classic", then don't you think this thread deserve to be on Tekkit Classic section?

Sorry like I said first time poster.

So is there anyway to fix slot 171?
