Best economic option is thick walled mandrel bend J tube to a new repro or New Old Stock x-shell manifold. The thick pipe is important for longeivity, and new manifolds are less likely to crack than one thats seen 29 to 51 years of heating and cooling cycles
The stock foot ball pallet cat style S-shell/Fox exhast manifold on an earlier X-shell would be the best if the converter was removed and a good thick iron plate fixed on to allow a good turbo to sit between the spring tower and the exhast mainfold.
Linc's 200 used a stock early header and just used Factory Ford Explorer 3.0/4.0 100 thou mandrel bent exhast pipe to make a J tube to hold his Turbo on.
Other better options are to dredge up knock offs of Ak Millars ductile iron turbo headers for propane 200, 250 and 300 I6's. This nested the turbo aft of the stock manifold outlet, and where the starter would normally be on a 200 engine.

There was another type which mounted the turbo forward where the A/C would sit on some 200 engines. See
2000Scooby for how the Ak Millar kits were done for early Pintos

A few of Ak Millars earlier I-6 exhast manifolds are being found by collectors. His later brace of i-4 Pinto 2.0, Lima 2.3 and V-8 255 Windsor propane conversions done for Ford back in 1983 have resulted in a few sub 10 second Fox and Bobcat bodied Mustang and Pintos hitting the drags
