Hi ,6 speed
My suggestion to you is call , or visit your local salvage yard and have them check their Hollander Interchange Manual .These books have been around for years ,and will tell you what swaps with what . I think that '78-'82 Malibus are basically all the same ,and also ,Monte Carlos ,Gr.Prixs ,Cutlasses ,etc .are pretty much the same cars ,suspension wise in those same years .I would also think that springs for a wagon would definitely be a lot stiffer than say springs for a Monte Carlo ,so maybe swap in some lighter duty springs . Cut coils IMO are a definite no-no ,lowering suspensions can be tricky ,and cut coils is NOT the way to do it .There are enthusiast sites specifically for Malibus ,and I would take a look at that also ,to see what is out there for these cars . Just my $.02 worth .
