Olds to Chevy Swap

Taken the 83 307 out of Olds 98 and putting in a 87 Chevy 305 with 200R4 tranny. The Olds crossmember does not work. What vehicle can I get the right crossmember out of? Thanks.

There are several companies that make the x member, don't recall the name now but a google search will find them. They for the Cutlass body, so not sure if they fit though. You may need to fabricate one.
