I believe they are both 86s.  My sons only 2 1/2 so i got time to tinker with them. Plan to give it to him for his 4 th bday.  That manual would be a great start.  All i know is these things were supposed to be tough.  As far as the lack of suspension, i dont think hell be going over 15mph or so for quite a while.  Ill post some pics when i get them home.  Once i figure whats good and bad, ill part out whats left if anybody needs 50 parts.  I do know that i may need a tank or find a way to clean and recoat the inside of a steel tank, if thats even possible.
