How to change a signed transaction's version and sign again and broadcast?

The following transaction is made by an atomic swap wallet and the tx version is 2. This would work if it was for Bitcoin but it's for an altcoin with older code base where tx version is 1. Is it possible to change the version and sign again and broadcast? I tried changing the first bit from 02 to 01 and signed again but got an error. The transaction is trying to spend a BIP65 input and I don't have the redeem script for the script hash so I have no idea how to make it from scratch. Otherwise making it from scratch would do the trick too. Please HELP!

Code:

The coin is known as SwiftCash and its core is pretty much a fork of the older versions of Bitcoin.

This is the decoded version of the transaction:
