To be clear, I have build dates of 11/69 and 2/70. Thanks!

Per the TSB - the change over from Yellow to White was at HLS30 31643.  That would have been an 05/71 Date of Mfg.

Just reconfirming my interest in a set when you get to 1972. My build date is 2/72.

Thanks

Hey Carl, TS71-60 notes engine serial number L24-031643 as the effective number, not vehicle serial number. More likely about 03/71 vehicle date of mfg.

Hi.  I'd be interested in a set for a '70.  Any progress or timeframe?  Thanks.

Wow!  Put me down for a 1970 set too.  Thanks Roo!

@SpeedRooJust checking in to see how progress is coming along. Thanks!

Finally tracked down an original set of 1971 plug leads (had to buy a complete car to get them!), they are different to 1970 in having white lettering and the #6 plug boot with a 45 degree bend. Just have to model that up in Solidworks and print out a test piece. The 1970 wires and boots are all sorted and modelled. Print samples work fine on the test engine.

Thanks for the update!  Great news.  Do you have an idea when you'll have the 70 wires available for sale?  Thanks.

I would be interested to for an early 71 sign me up ( my car has lots of 70 features, so who says the 71 could have 3 different plugs wires in 1 year...

mine could have had the late 70 left over from factory stock, they put on early 71's, that was the practice back in the day...

Hi. Just shaking the tree. How is the project coming along? I’m in for one ‘69 and one ‘70 set.
