Holiday Joe

Hello my name is Joe and im new to your site. Just purchased a 1978 Holiday Coupe. Always into the big cars, it is a 350 with th350 .She runs like a clock but is an absolute sled with a 2.42 open rear. I have a BOP 4.11 posi out of 69 or 70 gto or cutlass. Would anyone out there know if I can use this in the delta? Any thoughts would be great. Thanks look foward to reading up on some things. Joe

Nope, it won't fit. But I'm sure you could sell that one for more than it would cost to get the correct posi for your car. Just to be sure, you said holiday coup but later said delta. So you have a 1978 Delta 88 correct? Years ago I had a 1977 Delta pace car and it had the 8.5" corporate rear end. If yours has the same one that would be way more common than the 1969-70 rear end. If you don't get a response soon contact a member named monzaz as he has a business that buys/sells/rebuilds rear ends.
