Stupid question of the day - Delco D106P points

[Gary S.]

This should be simple but ...
I have removed my ignition points of unknown origin (could even be Advance Auto for all I remember) and I am replacing them with new in the wrapper Delco D106P points. The unknown ones at the bottom of the photo use the screw to connect the two leads to the spring arm. Does the Delco unit require one to set the leads between the gray plastic clip and the metal arm? If so, is there an easy way to do this? This is crazy unless I am truly messing this up.

Here is an amazon link to a D106P clearly showing the lack of attaching screw. https://www.amazon.com/ACDelco-D106P.../dp/B000C9P2UM

Gary:

Delco Remy DP-106 also has a similar points set that uses the screw. It is called DP-106PS. Either is acceptable for use and should provide good service life and performance. Some prefer one type over the other. FWIW, I prefer the one without the screw.

After installing the points, simply push the spring away from the gray support and insert the condenser lead and the incoming lead from the coil. They should be arranged so that the wire tabs on each lead point away from each other so that the two leads are flat between them. This would be the same if a screw was used as well. It ensures a good connection to the points set that is not cocked or off-set.

Hope this helps.

Larry,
Well I got it done but it was pretty tight quarters working under the advance mechanism. I can see why some prefer the screw type of connection. Good point on the tabs - I can see that having them the wrong way would be a problem.

I do have a uniset of Blue Streak DR3575CXP points coming so that will make the next change easier. I had seen the DP106ps and assumed that the S was for screw but I already had the standard ones.

Thank you for the help.

Gary:

Many.........including myself.........do not like or recommend the uniset points and condenser. I personally like the separate points and condenser and have always used the Delco DP-112 SHP points myself, which only come separate. I believe the failure rate of the uniset was an issue back in the day, but it has been too long ago for me to remember all the details. But they may work well for you.

Re: Stupid question of the day - Delco D106P points

If I'm remembering correctly, the other downside to the uniset type is it uses one less screw. So you end up removing the screw to install the uniset, then lose said little screw, and now if you ever want to go back to separates you have to scrounge a screw.

Re: Stupid question of the day - Delco D106P points

My searching here suggests that the Blue Streak unisets seem to be acceptable. Oth, I only changed my aftermarket points for a Delco unit. I really appreciate the comments and opinions.

Jack, hadn't thought of that. Thanks

Re: Stupid question of the day - Delco D106P points

I've used unisets for years... Simpler, more serviceable, fewer wires, fewer modes of failure- just a better design IMO.

My favorite is Blue Streak DR-3575CX. They have a cam lubricator, standard spring tension (so no extra wear on the cam) and look like copper jewelry. No longer made but can be found in their sealed packaging on eBay. Apparently some guys buy out the inventory when a parts store goes out of business, then sell the stuff individually on-line.

Over the years, I also tried no-name, generic points and condensers which looked cheap in comparison to Blue Streak. No noticeable longevity or seat of the pants performance difference, but I tend to change points early in their life and shift shy of 5000 rpm (oval port big-block).

I much prefer the Uniset type points for a number of reasons:

1) Uniset points have a condenser matched to the point set. This greatly reduces metal transfer from one of the contact points to the other;

2) The alignment of the contact points is better and the Unisets have features to better ensure that this alignment is maintained for the life of the point set;

3) The Uniset design reduces radio interference

4) They are easier to install

I'd never go back to the old style separate points and condenser. Never.

Joe & Mark,
I had seen your responses before from a search on this site. I was alluding to those comments when I replied to Larry. I have a NIB set of Blue Streak uniset points coming.

I corrected my original post as well.
