Hi Mark, the ‘92 Daihatsu Hijet is a very cool little truck!
In most cases, you would be able to place your vehicle with an insurance carrier specializing in collector vehicles like Hagerty or Grundy. However, since you mentioned it would be your daily driver, they may not accept it. Usually, collector carriers will only write a policy if you already have an underlying policy for your regularly driven car.
The other option is to find a local broker. Once they have the specifics and understand the situation, they can negotiate a policy on your behalf with the correct carrier.
