no needs for a conversion mount. you just need the factory v-8 mounts. the k-frame is the same for a slant and a v-8 in an early abody.
if you can't find nice used mounts then you can get them new from schumacher.

exhaust is the other pain in the ***. this is what the factory manifolds look like.

i know other manifolds will fit in there but with power steering it it may be tough to find a set that fit other then the original type..
do you have a v-8 trans yet? if not you need one of those also because the slant 6 one will not bolt to a v-8. do your self a favor and stay with a 904. it fits those cars a little better.. does that car have a push button automatic? if so you may need to get an aftermarket shifter for it too. a v-8 pushbutton 904 is getting harder and harder to find...
