You can likely find pull out motors for less than what a rebuild would cost. Drop a complete motor in each truck. I've heard pull out long blocks for as low as $80. I have purchased multiple complete motors with harness/computer and trans with low miles for $1,500 to $2,500.
I have a 55 big window I plan to do as well, except changing the cross member to hang all new (new to me!) suspension from. I don't want to mess with cutting up the whole clip and making new attachments for bumpers and sheetmetal.
