Where to purchase replacement sway bar bushings 69 older B

A friend of mine is looking to replace his sway bar bushings on his 69 Road Runner. It appears most shops have 70 and later. Any thoughts on where to purchase reproduction ones?

The only ones that fit that type on the 69 down that I have found were poly replacements and they are not easy to replace , welding may be required.

Energy Suspension

I 'think' I bought a set from ESPO at Carlisle some years ago. Also Poly..

That's it, couldn't remember the name of the company.

Vinny , measure the bar diameter , I think they sell more than one size ?
