find columns with same headers in multiple worksheet and coping column in new sheet

i have workbook, where i need a macro that he finds columns with same headers, and he copies data new sheet. colomns in different order in sheets. this is my code, he works with the sheets that that have same order of columns

Sub Merge_Sheets()

  Dim startRow, startCol, lastRow, lastCol As Long
Dim headers As Range
Dim ws As Worksheet
Dim pas As Worksheet

'Set Master sheet for consolidation
Set wb = ActiveWorkbook
Worksheets.Add(After:=wb.Sheets(wb.Sheets.Count)).Name = "AllSheets"
Set mtr = Worksheets("AllSheets")
Sheets("Sheet1").Activate
'Get Headers
Set headers = Application.InputBox("Izaberi opseg Header-a", Type:=8)

'Copy Headers into master
headers.Copy mtr.Range("A1")
startRow = headers.Row + 1
startCol = headers.Column

Debug.Print startRow, startCol
'loop through all sheets
For Each ws In wb.Worksheets
     'except the master sheet from looping
     If ws.Name <> "AllSheets" Then
        ws.Activate
        lastRow = Cells(Rows.Count, startCol).End(xlUp).Row
        lastCol = Cells(startRow, Columns.Count).End(xlToLeft).Column
        'get data from each worksheet and copy it into AllSheets sheet
        Range(Cells(startRow, startCol), Cells(lastRow, lastCol)).Copy _
        mtr.Range("A" & mtr.Cells(Rows.Count, 1).End(xlUp).Row + 1)
           End If
Next ws

Sheets("AllSheets").Activate
End Sub

my macro is in private workbook

Please post a sample workbook: instruction in yellow banner at top of page.

i modified my code and this code works with range A1

Sub MasterMine()

Dim Master As Worksheet
Dim LR1 As Long, LR2 As Long, LC1 As Long, LC2 As Long

    headers.Copy Master.Range("A1")
    LC1 = Master.Cells(1, Master.Columns.Count).End(xlToLeft).Column
