Looking at a rwd swapped Daytona. It has "stock" front end under it. Does anyone build a drag adjustable, strut to fit these cars?

Here is a pic of how it was done on a car I had. It had Santhuff struts. Bottom was connected to the stock Daytona lower A-arm. I don't have a picture of how it was done.

Mine had the stock clip under it and had adjustable struts. It appeared as though they were for something else because they had spacers at the top. I don't remember any brand name on them.

The ones I had seen used either a modified stock front crossmember or a fabbed one duplicating the critical dimensions but leaving room in the middle for the engine and trans. Aftermarket support for these cars is in the toilet and only going to get worse over time, if you're fabricating something I would be looking at re-configuring to accommodate generic aftermarket parts instead.
