Just the front ..or front and rear..what year model vett do you have?..there's several nice builds going on here now on the tf trucks..ive got one im fixing to put in my ad truck with the flatout crossmember..its close to the same process on either body style.

85 C4 in my 58 Cameo, Used Flat Out Engineering's kit and very happy with it,
bolt on rear with a weld in front cross member.
Worth looking into if you are planning to go with the C4 components.

I would like to use the c4 cradle it looks like it wouldn't be too bad to use . I thought about boxing the frame then adding two plates on the bottom so the suspension would sit square in the chassis . I have already got the frame sitting level with all the brackets removed I think I should sit the cross member in at 3 degree similar to a mustang II .

I plan on front and rear suspension with front oem cradle for it

look at canadian hotrods site from Tappen BC Canada, they have an awesome looking frame all computer cut and jig welded. US dollar is good too. good ideas if nothing else.

Over on the tri-five forum there's one with stock vette cm, search for Germain's post. Mine has flat out front and rear.

Thanks for the info guys

The stock vettes I have worked on state that the lower A arm should be parallel to the ground. I have out of a 92 sitting in my garage and that seems to be true on the 92. The front of the upper A arm will be tilted up quite a bit. The flat out kit for the pick up also states the same thing.

There's a few threads here on using the stock C4 cradle:

I did my own back-half. Secret is have the dog bones intersect the instant center line for neutral squat/anti-squat. center on an IRS is from the center of the rear wheel to where the CG height intersects the front wheels. Check out this link:

Easy way out, order the installation kit/cradle from Flatout Engineering. They already did the hard work, engineering and geometry.
