I can't recall where I read it, but someone that diesel repowered a Cherokee used the boost guage from a Chrysler LeBaren or such from the same era that fit into the Cherokee guage cluster.

From Wiki ; intercooled version of the 2.2. This engine was first used in the 1986 Shelby GLH-S, and a different version, with changes to increase durability, was produced by the factory the following year.[2] Shelby installed it in his updated 1987 GLHS, as well as his Shelby Lancer and Shelby CSX. Chrysler's strengthened version of this engine, with a forged crankshaft and connecting rods, was used in the Shelby Z package of the 1987–1988 Dodge Daytona and, later, in other cars
