So I pm'd mklotz70 about his downpipe flanges, but sadly he no longer sells them. He graciously provided a link to his site with further links to CAD and pdf of the dimensions. I took the CAD and uploaded to sendcutsend.com

To get above the minimum order without additional fees, I ordered 3. I will keep 1 and sell the other 2 at $20 shipped continental US. Cost for 1 (not meeting the min.) is $17+ from sendcutsend.com so its cheaper than you could do through them. Ordering 3 brings the cost to $11.65 per. not sure what shipping will be but I think $20 shipped is reasonable and covers my time at the post office...

Estimated ship date to me was 7/12. I'd turn them around as soon as I get them. Let me know if you are interested and mods, please remove if this crosses any lines.

paypal or venmo when I have them in hand

cheers,
