Combining Two fixed width columns to a variable length file

Hi, I have two files.


File1 contains two fixed width columns ID of 15 characters length and Name is of 100 characters length.

ID Name
1-43<<11 spaces>>Swapna<<94 spaces>>
1-234<<10 spaces>>Mani<<96 spaces>>
1-3456<<9 spaces>>Kapil<<95 spaces>>


File2 contains two fixed width columns ID of 15 characters length and Name is of 80 characters length.

ID Place
1-3456<<10 spaces>>Boston<<74 spaces>>
1-43<<11 spaces>>London<<74spaces>>

I need an output file of variable length file as follows


The Output file should contain the matched records of both File1 and File2 based on ID column.

Id Name
1-43<<1 space>>Swapna
1-3456<<1 space>>Kapil

Thanks in Advance.
