How is the expansion tank on a 1970 small block with a/c mounted? I cannot fit it between the inner fender and the a/c lines coming from the firewall which is where I believe it is to be mounted.

Re: 1970 EXPANSION TANK
1970 small blocks. The only 70 small block to use an expansion tank is the base engine with manual transmission with no A/C. All other small blocks for 1970 had no expansion tank. See the 3rd edition of the Judging manual 1970 - 1972 page 92. List's all models with or without expansion tanks and types of tanks either aluminum or brass.1967 L79 Sunfire Yellow Black Leather Convertible- Duntov
