How close is to close

My son's is about 1/4 of an inch. It's been that way over 4 yrs, and he is a very spirited driver. The engine's forward movement is limited by a chain, so the rad's gonna hafta move back, and only a full frontal impact might cause an interference, meaning bodywork and rad may be in order.. lol

No shroud, no overheat, even on hottest summer day.

This is a stock 7 blade clutched motorhome/van unit, the wrecker had 3 on the wall .. $30 each..

hope it helps . . cheers
