Tackle issue about wagon for frontiersman (3,6)
I believe the answer is:
kit carson
'frontiersman' is the definition.
(I've seen this before)
'tackle issue about wagon' is the wordplay.
'tackle' becomes 'kit' (both can mean gear or equipment).
'issue' becomes 'son' (issue can mean someone's offspring).
'about' says to put letters next to each other.
'wagon' becomes 'car'.
'son' put after 'car' is 'carson'.
'kit'+'carson'='KIT CARSON'
'for' acts as a link.
(Other definitions for kit carson that I've seen before include "American frontiersman - is on track (anag)" , "one 15 [PLAYING] 24 33 [AT SIXES AND SEVENS]" .)
