I pulled the 700/241 from my 90 K5 and I'm replacing with a 400/208 setup for now. The 241 had elctric speedo & the 208 doesn't. How do I get around this? Will running with no speedo be a problem for the elctronic sh!t? Looking for a simple & cheap fix as the 208 comes out this winter for the 203/205 double setup. Thanks.
