We’ve written a new ‘How To’ article, with clear pictures, for the Stromberg Tech Center on how to fit our new 9139K Throttle Shaft Extension Kit. If you’ve got one of the old school 4×2 intakes that stagger the 97 carburetors close together, like the Weiand WC4D and Edelbrock CD-694, or if you have a new blower plate for mounting your 97s on top of a GMC-style supercharger, this is the kit you need. To download the ‘How-To’, just click here. We’ve also posted the pages below. Click the first page below then click on the page to move to the next one.
