Mini Car Wars

[The Horn'd One]

OK, I'm relatively new to these boards, & recently I purchased the PDF of "Mini Car Wars" from the site. While this product reminded me of the first time I played Car Wars, I noticed that it did not contain the "Fifth Edition" variant rules, for use with small scale (Hot Wheels/Matchbox/ect.) sized toy cars.

Since I am planning to try out a short test-play with these rules, I need to know what I need to change in the Mini-CW rules to make them compatible. Can anyone help out? Is there an Errata?

Thanks in advance. May the highways you drive be clear.
