Thanks Ken.

Yeah, a 9" dual diaphragm booster with a 1" bore manual master cylinder. I think the application was an early 70s Corvette.

Colin,

I have been so busy I have not had much time to work on the car but I am trying my best to get back to it. I asked you about the brake booster you choose and I have looked for an early 70s Corvette booster from Cardone and it does not come with the mounting bracket and the rod is way to short. Is this what you ran into as well? Did you go to the aftermarket for a bracket and rod extension kit? If not and it was a direct fit you wouldn't happen to have a part number and source for the one you used that you can pass along by chance?

Thanks again for all your help-Ken

[CFster]

Ken, I used one of two brake booster extension rods - I bought two and I don't remember which one I put on the car.

Part #6474SRBDP

and

Part #6474SERBSP

They're both available from Summit.

I'm not sure what you're talking about with the booster? It won't bolt to the firewall?

Robbie, try PM'ing me again with the number. It didn't come through. Thanks.

Colin, The boosters for a Corvette that I found did not have a mounting bracket and the rod was short. I may have looked up the wrong year application. Do you remember which booster application you used. It looks like a '79 or so Trans Am with 4 wheel disks application may work. I am having a hard time finding one "on the shelf" locally though. I hate ordering things then having to send them back, yuk!

Thanks again-Ken

[CFster]

Ken, I'll see what I can come up with this weekend. I know the booster and master are for an early '70s Vette.

[CFster]

Installed some J-pipes. They help with exhaust drone significantly!

[1989GTA]

What length of J-pipe did you go with? They look to be 2.5" in diameter.

[CFster]

They're actually adjustable length, so you can tune them.

Got them from Solo Performance --> http://solo-performance.com/

Thanks for the link just incase I need them for my car.

i just when through your thread again.

I have the front end off my car and have spc uppers installed (not setup up or adjusted). I am wanting to start working on my clutch master and when I set my driver side inner fender in place it seems like I have clearance issues with my upper rear bar on my SPC uppers...

did you have any issues, or do I just have the angle of the dangle wrong since I don't have anything to support the front of the inner fender...

I can't find anything about the adjustable j-pipes on their site and I need it desperately. Would you mind finding the direct link, or do you need to call? Thank you

No problems with clearance here.

Just call. They can make up J-pipes to fit anything.

Decided to go with a slightly taller tire (45 vs. 40). I think they fill up the wells a little better and made a big difference in ride.

Hey Colin I am finally going to order wheels and had one question....how much tire bulge do you have on the rear? I want to get as close to the inner quarter without rubbing and maybe leave a 1/4" or so for good measure but I really need to know how much tire bulge to expect with a 275/45 tire to ensure I get the backspacing correct.

Thank you again-Ken

[wayward]

I have a huge favor to ask, if you could do I would greatly appreciate.

Working on my front inner fenders and having problems with my spc adjustable and clearance...

I have the Long shaft in the front with the welded tab up front as well...

Could you give my some measurements from you upper adjustments. Say possibly center of ball joint to center of bolt that attached the bracket to the cross shaft...

I'm just looking to get in the ball park and identify if I have done something wrong before I proceed any further.

Not much, but enough that it rubs sometimes - there's no way in hell I could get a 285 in there and not have it rub constantly. I don't know about other people. Mine rubs when there are more than two people in the car going around around corners "briskly". IMO, unless you have a Watts link 1/4" isn't enough clearance. The rear moves side to side quite a bit under even normal driving conditions - and you know what I bet the johnny joints are partly responsible. The factory arms and bushings bind, which is a bad thing in of itself, but the joints allow freer movement...

Sure I can do this, but I won't be near the car until tomorrow or Wednesday.

Have you called Marcus?

Mr CF

I have been studing your build and had a couple of questions. I have a 64 tempest.

You used the autocraft pan and edelbrock mount, same as b-man on his 64 tempest project (Don't recall what mounts he used) but his inner tie rods were hitting the oil pan. I didn't see any discussion or pics if this was a issue with your car. I have seen a few others oil pans that look pretty nice too. Wondering what other pans did you look at before deciding on the auotcraft. Is there a oil pan motor mount combo where you don't have clearence the floor pans as much?

You decided not use these mounts, correct?

Also what was the reason for going with the external pump? How did you tie into the gas tank with the return line. I assume you have no baffeling in the tank? Have you ran into issues with that?

I love the build and it looks like it was well thought out and little expense was spared on the LS conversion.
