Evans and Year One....Evans makes theirs in-house and Year One is the licensed distributor for M&H. If you can wait for a 30% off special from Year One I would go that route.
I haven't heard anything on the classic one.I used the Year One that is manufactured by M&H,it was very expensive but the quality was awesome and worked as it should,I have no regrets now.I installed it on my 69 GTX. Joe
We used YearOne (M&H) rear wiring harness for a '69 Cuda and found that 2 connectors were female instead of male. M&H promptly apologized and sent the correct connectors and terminals that we had to install (no big deal if you have experience) Other than that - very impressed with the quality of the harness.
