B42 I looked at... in Antique and Classic Mack Trucks General Discussion Posted April 5, 2015 · Edited April 6, 2015 by mattb73lt Maybe if it was restored and re powered. I agree with the others around $2000. I payed $1600 for mine as a rust free B-42 cab and chassis. Then repowered the whole thing. The 237/5 speed mentioned would be perfect way to go and a good price mentioned above. That guy needs to stop smoking whatever he has been. That frame is predrilled for diesel mounts and front crossmember by the way.
