1979 olds cuttlass

Yes, DoubleV loves Sanderson. He got 3 bad sets, I got 3 good sets. I would go the Thornton route if I were to do it over, cost for cost. Ram Air Restorations and Pypes makes down pipes that will work with the Thornton shorty's but are more geared for A bodies and the double hump cross member.

Have a part number on the down pipes?

Pypes, a by time crap shoot. https://www.summitracing.com/parts/pye-dof10s
Ram Air Restorations https://www.ramairrestoration.com/sho-6-2-5-mandrel-bent-headpipes-flanges.html

All the above are good in my book.

Ive utilized the Sandersons in the past for the Olds that I had and they worked out just fine. Ive also used the Thornton stuff with good luck. Ive even worked with the Pypes down-pipes for a custom Olds exhaust with a successful outcome..

If you already have headers, I wouldn't be afraid to clearance the shift linkage. Looks like there's plenty of meat there to remove.

How about cut off the 3 bolt gasket flange and replace it with a 2-bolt ball and socket flange to match collector diameter? Might move connection point for linkage clearance and more ground clearance than three bolt.

America racing headers makes them I have a bbo in my 79 cutlass they fit perfectly but their pricey but worth it

Or, cut off the 3 bolt and use a band clamp. I love band clamps.

That is another bonus of the Thornton shorty's, 2 bolt flange with no gaskets and accepts early Olds down pipes. One member on here used sbc downpipes from Pypes but one needed modified, surprised they even bolted up. I wish they made a Chinese Stainless full length copy for a G body, putting a set on my 70S. I already have a custom 2.5" system with Sanderson's, they just clear the brake lines and need aluminum or copper collector gaskets but just RTV around the heads.

I have the thorton 350 jr on my 307 With copper gaskets. Fit perfectly. I am very happy with them
