Sierra to Cortina uprights

If i change the front uprights from Sierra to Cortina what else do i have to change, i´m thinking of change to Hispec lightweight ones with Sierra hubs. Any one know if the Wilwood brakes will still fit or if the wishbones, upper and lower, must be replaced, or is there any other issues.

I think there are major differences in geometry between the two so you will be looking at a full suspension redesign.

The Wilwoods will fit with different brackets and spacers.

My car was designed to use Sierra but I initially fitted Cortina (cos I ordered a Cortina chassis but it was made wrong) couldn't get any ride height at all, until I swapped to Sierra uprights, then had to get new brackets and spaces to fit the brakes.

So yes new wishbone will be required.

Thanks for the answer, since I´m going to change to rose joint all round i take my chances with the Hispec uprights and rebuild the wishbone as i change to rose joints.
