Topic: 68 FE bolts for Brackets

[68 S Code]

Well getting ready to finish off the front of the 390 with the alt and ps pump. Need to mount the brackets and want to use the right bolts. Have lots of bolts but not sure what should be going on. The assembly manuals really dint give me much clue as difficult to decipher. A pic or two with a clue on bolt finish would be very helpful.

The 3 bolts that hold the pump to the bracket and the pump adjuster are phosphate generally have a dimple in the center. Long bolt has either a cad huglok or a phosphate pinch lock however some early cars have been found to have zinc pinchlocks 
Alt, long bolt cad, adjuster bolt cad, brackets use zinc dichromate on the place bolts. Smog adjuster is zinc dichromate

Tim thank you. I think I guessed correctly. The phoshate at the ps bracket and the ZD at the alt/smog bracket have sort of cuts in the head, correct? Are there normally split washers behind the heads? If yes are they zinc?

[TLea]

The ones with slots in the heads are called place bolts. This is what I usually see on PS pump side,


Hard to see but the place bolts on the alt/smog brackets are zinc dichromate

Tim thanks for these pics. The ones I sent you of the alt/smog side were ZD place bolts at the bracket and I believe there would be another which would mount the smog adjusting arm/canister bracket. The flash on the phone camera made them look bright zinc but they are ZD. But looking at the PS bracket side your pics dont seem to look like phosphate place bolts. They look like phosphate bolts with a flange head. Similar to the bolts which mount the pump to the aluminum bracket. I did use the place bolts to mount the bracket to the water pump (phosphate finish).

Tim is this a pic of a 70 CJ? Unusual carb. Is that an Autolite? By the way the brake booster vacuum tube is not painted. Is that the way it should be? Unpainted on a 68?

[TLea]

They are the same phosphate RBW bolts that mount the pump to the bracket. Thats what I've always seen there. Regarding the motor. It is from a 68 GT 500. I highly caution anyone to copy details without knowing the specific application. Yes that is an Autolite 4100. There was a period of several weeks around Jan 68 that the 500s did not get the Holley carb installed like they were supposed to. This car is one of them and documentation was provided. Booster line and rear intake vacuum fitting are unpainted on GT 500/ GT 500KR

Thanks for the clear up of the PS bolts. I have a few extras so I will swap them out. Regarding the rear booster vacuum tube I presume that on a 390 it should be painted. I have a couple of odds and ends to shoot engine blue and want to mix paint only one more time. The bolt which mounts the canister bracket seems to also be blue and it is a flange bolt? So yes or no on washers at the alternator place bolts? Thank you for passing along your knowledge.

On the rear of the manifold are 2 brass blocks. One threads into the block and the other threads into that. The second one is the one the booster tube goes in. The one that threads into the manifold is painted blue with the engine, the other is added later so it is natural brass. The booster tube is also unpainted. Looks like this even though its a 428,


Cannister stand bolt is just the water neck bolt which has a recess in the head and yes it is painted.

PS: the exhaust manifolds should have overspray, I did not have it done at the point this picture was painted

Thanks for all the info. Regretfully the engine builder did not overspray the manifolds as they were out getting coated. Look great! He installed the engine so touching that up would probably be disasterous. You know how tight it is in there. The bright side is that at least the motor is painted thouroughly with no missed spots because the exhaust manifolds would have been on  ,well almost.....somehow they missed the bottom of the pan which drops down .

Tim that saw isn't going to make it fit any easier

By the way in this rear shot the bolt for the trans tube is a ZD place bolt. Thought it was supposed to be a phosphated RWB bolt? Thats the second pic I've seen with the ZD bolt. Which is right?

Maybe not so regretable after all. Recent contraversy has challanged some of our long assumed beliefs of wether or not the BB exhaust manifolds were painted like the SB exhaust manifolds were or not. Recent evidence points to they were not painted but installed after the engine was painted (BB only) I would not paint any BB exhaust with blue overspray until the jury is in. You can always shoot a little overspray on them after the install if you had to even in a Mustang body. Bob

Then for now I wont even worry about it. Thanks Bob.

[TLea]

Bob, aren't the manifolds in question just the CJ ones?
Regarding the ZD bolt, thats for the ground wire.

[68 S Code]

Tim the hole you have the bolt in I believe is for the dipstick tube for a C6. Would the ground wire be mounted in the hole over to the right and down a touch?
