Legendary 66 barracuda seats questions

Did you end up needing the horseshoe foam? I am about to place an order and I want to make sure I have all I need. Thanks
I bought it... but if you have a foam shop or fabric store it might be worth it to see what hi density foam they have... I can get more picks and measurements tomorrow.
I believe the seat covers work ok without the extra bolster foam but it does not fill out the edges and wrinkles a little.
