I suspect finding a good example to rebuild might be a challenge. They saw a limited production.

The inline 8 first showed up in 1931 Dodge and Chrysler high line cars, but the Dodge ended inline 8 production in Jan 1933.

Chrysler Imperial inline 8 started production in May 1931 and continued production through the high line Chrysler models until the end of the 1950 model year production. Beginning in 1948, all inline 8 were equipped with the fluid drive semi auto trans. The inline 8 was replaced with the Hemi V8 with the beginning of the 1951 model year production. According to the Standard Catalog of Chrysler, 1924-1990. There were no inline 8 specific production numbers.
