Motor mount question 82 4x4 bb to sb

[blazin71K5]

The clam shels on the motor are different from 2wd and 4wd. The 4wd is more shallow and has a 3/16 thick triangle spacer between the block and clamshell. 2wd clam shells will not work due to the spacing of the k member in a 4wd. Once you have a set side by side you will see the difference, Bbc, sbc and deisel 4x4 clamshells are all the same for the 4x4 and will work. -Matt
