I have a 1974 Triumph TR6, 1992 5.0 HO V8 swap, AOD trany, converted to carbs completed May 04. ( she will snap your neck in all gears! What a rush!)

I'm running the stock IRS but I know that will not last long! Back in Nov.04, a complete 1984 C4 rear suspension fell in my lap, so
I'm making plans to narrow and install.

The C4 is 60" wide, the TR6 is 50", I plan on using 2" wheel adapters to mate the Chevy pattern to my Panasport wheels, so I think I'm looking at 7" per side.

My question, is it possible to narrow the C4 that much?

My local hotrod club members say to sell the half-shafts and get custom steele half-shafts made. Any thoughts?

Should I try and get a custom rear spring made or go with coils?

My goal is to have a stock looking TR6, performance road car, with modern features. A sleeper that I can enjoy on the back roads of WV, OH, and PA.

Thanks for any info or leads.
