Importing Records From Text File Based On First Character Or Code In One Field

I have a file that I need to import on a regular basis. There are two different issues with the import:

1. the first digit in the file indicates if it is a record I want to keep. In this case a 1 indicates a repair record and an 8 indicates it is just information such as email, contact info etc.

2. I have a field in the file that may change the import specifications

For example:

If the record is a Non wheel repair then column 167 is a 50 character description
If the record is Wheel repair then column 167 is a 28 character description and the remaining 22 characters are broken down into 10 different fields

So I need to do the following

1. Read the first character in the line and determine if it is a number 1 and if not discard it
2. Read a field in column 109 that is two characters long and if it says it is a wheel repair the import will break column 167 -216 down to the appropriate 11 fields and if it is a non wheel repair it will import columns 167 - 216 as one big description field.

I have used the import specifications with Access but it seems this will have to be done in code in a module or something and I am not very good with VB. (only know the basics)

One other issue is I have dates in the file that are 130225 and 1302 (so full date and then Year/Month) if i take out the / date separator in the import spec the full date works but the Year/Month doesn't.
