I really enjoy reading your thread. It has been one of the projects that motivated me to go forward with my LS swap in my Pontiac. Did you ever get a chance to weigh the car again to see the difference? My car will still be heavy even after the swap. Great work!

Sorry haven't had a chance to weight it again. Have to re-borrow the scales...

when you measure your rear housing is the 57 3/4" wide flange to flange or brake face to face?

Thanks...

Eric, that's outside flange to flange.

I just wanted to say this car is beautiful! Love the setup. I am ready to order wheels and tires for my 1966 Lemans Sprint ohc6. I am going to shorten the rear end after I get wheels to assure fitment. My question is...Are you sure of your rear wheels backspace. They dont look like they have 5.75in. The baby blue car from prodigy that has 19s in rear is running 19x9 with 4.25 bs. Another member on here (quoted below) is running 18x9 with a 5.75bs and his dish on the wheel looks way smaller. I am just trying to get a good baseline before I order wheels. The rear end is out of my car and torn down so I cant measure now.

Attachment 75416 Attachment 75417 Attachment 75418 Attachment 75419 Attachment 75420Here are the final wheel pix! Final stats: front 18X8 Billett Specialties MAG G 5" back space,245/40/18 NITTO MOTIVO tire. Rear 18X9 5.75" back space, 255/45/18. 275/45/18 tires will fit as well. This car has stock wheel wells and rear end. CHEERS!

Hello Colin,

I was wondering what did you finally do for E-Brake cables?
Anymore plans for the Goat? Are going to autocross it?

Thanks as always Ken

Haven't worked out e-brake cables yet. Working on other projects at the moment!

Sorry about the delay. Your best bet is to ask a reputable wheel guy on this board. They'll know the right measurements for A-bodies. We changed my rear axle width and wheel backspacing mid-order. What's on my invoice may not be correct, and I haven't had the chance to physically measure them.
