Windjamer14 Posted March 15, 2018 Author Share Posted March 15, 2018 The one I have states it for 350th or 400th but its a little short of bolting up it's plastic which I think is right for that year ? Quote Link to comment Share on other sites More sharing options...
joseph Posted March 16, 2018 Share Posted March 16, 2018 all of them i ever saw are metal. maybe the heat distorted the plastic. go to a junk yard and find a metal one that is what i would do. no plastic. Quote Link to comment Share on other sites More sharing options...
Paul Bell Posted March 18, 2018 Share Posted March 18, 2018 I got this one. It's steel, gold cad and the vents let some cooling air in and if there's any, drippings, they get out instead of just sitting there. https://www.ebay.com/itm/ZINC-STEEL-FLYWHEEL-FLEXPLATE-COVER-FOR-CHEVY-GM-TURBO-TH-350-TH-400/122340818391?hash=item1c7c14bdd7:g:~WoAAOSwLEtYlOCy&vxp=mtr Quote Link to comment Share on other sites More sharing options...
