W126 Subframe Swap?
W126 Subframe Swap?
The w123 and 126 subframe do not interchange. The 126 is wider. The 2nd Gen and 1st Gen subframes share the same front mounting. The 1st Gen rear mounting is located in the middle, while the 2nd Gen rear mount was moved to the left a few inches. I do think you can relocate you bolt holes to make it work.
