Early A / Gen3 Hemi Header Options
EDIT: After looking at pics of those SRT8 manifolds on the motor, they may be too close to the T bars to work.The best, but most extensive mod is most likely a Mustang II front setup and moved inner fenders, or struts.
There are ways to eliminate the torsion bars with coilover shocks, but then there are some K frame interference problems to deal with. The coilover conversion with some extra support for the upper shock mount like the Alterkation setup has may be your cheapest route. Somewhere there was also a thread on making a rear support for the Rear of the lower A arm to replace the support lost from removing the T bars.
I will have a lot more info on what will fit/work this fall, as I plan to start building the new coilover front/5.7 combo with SRT8 manifolds then.
