I read posts where certain cars came stock with rear boxed arms. Which rear stock boxed arms will fit my 66 buick skylark? This of course assumes I'll be able to find them.
I believe any A body from 64 to 72. They are an option so you can't tell by just looking for a GS, Super Sport, GTO or a 442, or other A body models. - Bill
Yep. Any '64-'72 boxed lowers will fit. My '67 came with the holes drilled, but were not boxed. I picked up a boxing kit on ebay a while ago.
The F41 option Rally Suspension which gave you boxed lower rear control arms and rear sway bar was optional from 68-72 GS cars In 68-69 also included quick ratio steering box. Only GS car EVER that had this as standard equipmentwas a 1970 GSX
I would just take the arms from your car andfind a good welder buddy and then box them yourself. Your not going to find an inexpensive set of boxed arms IMO. Mine came out great and we did them in my garage and I'm no pro welder!
