L16 Downpipe Exhaust Flange

grabcad

8/21/23 While working on a similar part, I found this one wasn't as accurate as it should be. I've just recreated it and it looks to be perfect now. The jpg is the old one, but the rest of the files are the updated ones.It was brought to my attention that the dxf file was wonky. It should be fixed now.This is for the 4 cylinder L-series downpipes that Datsun used through the 70's. Most exhaust shops can easily make a downpipe with this flange, they just can't make the flange. The pdf can be used a a template to make one manually. The dxf can be used with plasma or laser cutter. The stp file can be used if you want to mill the flange. I"ve included a video link showing previous ones I've worked with. I had SendCutSend make some from 3/8" HRPO so that I didn't have to deal with mill scale, they don't seem to offer HRPO anymore, just HR.
