Not sure how I missed this, sounds very similar story to one I had some wheels made for.
Customer got it from a Hanger down south, where it had languished for 10-15+ years. SBF, Renault Transaxle (open wheel non lsd) - he has a Turbo Axle he will swap into it. I think that particular car had some mechanical problem, a "mechanic" got hold of it with great intentions but no follow through until this guy got it. If I remember it was something like 5000km use in 25 years.
HQ Front brakes - He's dealt with Les Hunter for a Wilwood Caliper & Rotor upgrade. I guess because of the Renault Trans-Axle is the reason it was running 5/112 all around.
Was quite a tame SBF, think stock 70's 302 with smog manifolds & low compression, thats been pulled for a crate motor
He had a full big list of what parts from what donor cars were used in the various areas of the car
You can guess his theme;
