Topic: 1971 429 Alternator Splash Shield

[sah62]

Ed Meyer recently asked me about the possibility of reproducing the rubber splash shield used on 1971 429 Mustangs and Cougars. I did a little research and found a template on the 71 429 Mustang/Cougar Megasite:

I've attached a copy of the 10317 section from the final edition of the 1965 - 1972 MPC. I have some questions before I dive into this project too deeply:

• Does anyone have one of these shields handy to measure the thickness of the material? The template above says .100", but I can't get material in that thickness. I can get 0.800" or 0.125". Which is closer to the original thickness?
• I can find the D1ZZ-10317-A number in my cross-reference manuals (it crosses to an engineering number of  D1ZB-10317-AA), but the D1OZ-10317-A part number isn't listed in the manuals I have from the early 1970s. It does show up in a 1979 OSI manual, though. What's different about the parts, and what might the engineering number be for the D1OZ-A shield?

Can't be of any assistance - never found one on a car yet.  Would share that my fairly early Cougar that should have one does not have the mounting holes for it for some reason. Just mentioning since this might be something added during the year.

Good luck with the project

In examining your attachment it indicates 72 All V8's.  In review of the megasite I believed this to be a 71 429 piece only.  Is anyone aware of 72 applications of this piece??  I will reach out to some folks I know with 429's to see what feedback they may have on the part.

The 1972 info is for car line "S", or Thunderbirds. It's a different part.

Any luck? This is a very doable project for me, but I need to get the thickness right.

[nham3407]

Still awaiting response.  Let me email them again.  Sorry.

[nham3407]

I heard back from one of my 429 contacts and he has never had one of the splash shields in his posession.  He too has only seen pictures.  Still awaiting response from another person.

The engineering number for the D1OZ-10317-A is D10B-10317-AA.  I cant say what the difference is but with the different part numbers and different engineering numbers there is a difference for sure.  And keep in mind that a D1OZ was originally a Torino part or designed for a Torino but used on a Mustang for some reason.

I have access to a low mileage original 429 convertible and can look at that this week to see if the shield is still there and take measurements if needed.

[sah62]

Yes, please, Marcus. Where did you find that engineering number?

[J_Speegle]

IF not next best guess of thickness might have to come from a similar pieces on another Ford line

I will go and look at the car on this upcoming Monday or Tuesday.  Owner is out of town till then and then I can see if this piece is still on the car.

I also agree with what Jeff says here that there is probably plenty of other pieces on the cars of this period that used the same material...so one way or another should be able to figure it out.  I can always take a walk over to Desert Valley Auto and look thru there as well.

I know of at least two different parts (the 67-70 Mustang rear lamp shield and the front bumper/stone guard shield used on 1969/70 Shelbys) that use the same material, but the thickness is different. Finding an original part will make it a lot easier to produce an accurate reproduction.

What about early mustang under fender splash shields stapled to metal mounting plate how thick is that rubber shield?

In many examples that is more similar to the hose straps used for PS or heater hoses in the engine compartment - and not always a consistent thickness.

Scott yes your two examples are different thicknesses but they were designed and produced likely by different suppliers and for different purposes. If we could find a alternator splash shield on a early 70 Merc, Lincoln or T Bird  might be closer. Just a thought
