Modify powershell script to look for specific digits and write in a specific field

I would like to change this script so that when lookin at position position 99, it looks only at the last 5 digits and then writes those 5 digits in position 100...

Param(
	$filename = 'c:\Temporary\Import1.csv',
	$newFile  = 'c:\Temporary\Import2.csv'
)
$content = Get-Content $filename

$outRecords = @()

foreach( $record in $content )
{
	$array = $record.Split( ',' )
	## entries in $array are zero-based
	if ($array.Length -lt 101) {
		$outRecords += $record
	} else {
	     if ($array[3] -eq '65-ABCDEF' ) {
		if ($array[99] -eq "") {
		      if ($array[98].Length -gt 5) {
			$array[99] = $array[98].substring($array[98].length-6,5)
		      }
		}
	     }
	     $outRecords += $array -join ","
	}
}
$outRecords | Out-File $newFile -Encoding ASCII

		$outRecords += $record
	} else {
		if ($array[3] -eq '65-ABCDEF' ) {
			if (($array[99] -eq "") -and ($array[98].Length -gt 5)) {
				$array[99] = $array[98].Substring($array[98].length-6, 5)
			}
			if ($array[99] -match '\d{5}$')) {
				$array[100] = $Matches[0]
			}
		}
		$outRecords += $array -join ","
	}
}
