Pertronix 1864LA or 91864LA

[rjfurlan]

I have decided to upgrade the point in my early 1967 250sl to either the ignitor 1864LA ot the ignitor II 91864LA.
Any recommendations on either?
I have the 051 distributor and are not sure about the coil (it is a bosch and black).

If anyone in the future is interested, i went with the 91864LA and the Flame-Thrower II. I needed to file the bracket slightly but got everything installed in about an hour. It started right up. I took it for a drive and it runs wonderfully. It has never run this well since I have had it. I have not checked the timing yet, since it runs so well, but will. The idle dropped to about 500, so I will need to adjust that.

Go with the 123 distributor.  It's the best.
