1969 Boss 302 Question?

The 69 spoiler was plastic, and bolts went up thru the bottom...no reinforcement brackets were used in 1969..
The 1970 spoiler was fiberglass, and used the reinforcement brackets...

I can scan some pics if you need them..if you have the Donald Farr book, I believe there are some pics in there...

 

Hi all! Just a quick note:Realizing how rare a 69 BOSS is,I really would not recommend any modifications be done to original parts.A Marti report will confirm the original build-If you dont have one,get one before you make any changes.
The reinforcements you have are for a 1970 and as with most repo parts will not fit flat/flush as they really should for the added strength.They can be cut and made to fit with some tlc,this may be why they just have you hesitant to proceed.Study first..maybe even consider finding another trunk lid and preserving the original..Good Luck with your choice
P.D.

 

IF you choose to add here is a response I posted on another site last week for a guy looking to add a 69 to a 69 Mach I


---------------------------
Place the base gasket so that the rear edge is approx 5 1/8-1/4" from the top edge of the lip on the trunk lid and the outside edge of the gasket is approx 2 1/2" (shortest distance) from the outside edge of the trunk lid.

Tape the gaskets in place and use them as a template for the four holes. That it what I've done in the past

Also remember that you will need to form a small (approx 1/2" in length) round spacer to fit between the bolt head and the trunk lip top surface. If not, when you tighten it down you can crush the inner liner to the trunk surface or deform the trunk surface.

The 69 trunks do not have the oval cut out like the 70 but they also do not get the extra support that reinforces them to the trunk hinge arm area.

 

patty.dilabio said it best... don't alter the original part.. use a salvage yard part or repo to alter

 

From what I've found, I'm sure the original '69 and '70 trunk lids are different. The '70 has the oval hole for the support bracket to go threw were the '69 doesn't. I would also leave your original panel as is. Patty is correct, I've seen the brackets leave "half moon" dents on the trunk lid after the wing was bolted down. If you just have to have it, I would find a '70 trunk lid with the oval hole to do your alterations. Save your original. [JMO]

 

I also agree with most of the opinions presented here. Save the original and use a '70 deck lid. Once the holes are in the the deck lid, they are there forever.
