How to concatenate leading zeros on linked cells?

Sheet A (customers)
Over 2,000 customer listed

07.001 is the first customer with the last name beginning with “G”
07.056 is the 56th customer with the last name beginning with “G”

Sheet B (invoices)

Label	Cell	Value
Customer No	B317	07.056
Project No	J317	3510
Invoice No	A317	4620

Sheet C (ledger entry)

=CONCATENATE(‘Sheet B’!B317,”-“,’Sheet B’!J317,” “,’Sheet B’!A317)

 Result
   7.056-3510 4620

 Desired
   07.056-3510 4620

Question:

Within Sheet C, how to format the link to: ‘Sheet B’!B317
to include the leading zero?

I’ve read numerous solutions that reference using the TEXT function, but I cannot figure-out how to apply it to my situation on Sheet C, or even if that is the simplest solution.
