Perfect spacer

I used this product to add width to a set of t-bucket headers to clear the custom stretched S10 frame for a '34 chevy master I'm building. My requirements called for two sets to be used to obtain the clearance needed. Can be welded or use gaskets.

Good for the money

They were cheep so I can't complain but the two exhaust ports in the middle were not divided well material pinched between the two.

I had bought a set of Speedway SS Small Block Chevy Classic T-Bucket Headers that would not clear my 51 F1 cab. I wanted to do something different rather then cutting the headers and extending them so I made header flange extinctions for them to fit. Worked outstanding. This was the first time I welded mild steel to SS.I made them with the two sets of sbc flanges and one three foot 1 5/8 SS .065 wall tubing.

Awesome product at an awesome price!
