Insurance rates have been and are going through the roof. It pays to shop your policies every year with different companies. The best deal isn't always having both policies with the same company. The insurance companies have no loyalty to you as a customer, so return in kind and shop for the best rates for similar coverage.
As a side note, for our old mopars it would be a good idea to check with Hagerty or Grundy Ins if it is not a daily driver. They have good rates and I have handled claims for them both as an independent auto appraiser. They give good service and no hassle from my experience. Same can't always be said for big insurance companies with classic auto claims.
