## Questions & Answers

**Q: is this steel?**
A: Yeah it's steel

**Q: Does this cover actually weigh 11 lbs?  Seems like that may be incorrect**
A: Close to that.  It is Metal not plastic.  Had to do a little modification on this cover to keep it from rubbing on the fly wheel when you put full power to the motor from a stand still stop.  Other than that it works well to keep the flex plate protected form road debris.

**Q: Do you sell the bolts that attach this to the th350 or know the size?**
A: No the bolts are not included,  the bolts are 5/16"  x 3/4 " in length hope  that helps you.

**Q: Will this fit 77 Chevy El Camino**
A: If it has a 350 and I think it fits a 305

### ⭐⭐⭐⭐ fitment.
*by C***E on February 28, 2025*

product arrived as scheduled and appeared to be free of defects from shipping. However, the cover did not fit perfectly. You will probably have to grind or modify the starter opening hole just a little bit. Other than that, It bolted right in.
