Hi Ryder
Congrats on your decision to go with Warwicks car, I'm another Cobrakits builder.
Professor Merv has done a great job of pointing out common issues that you may want to address, however I haven't had issues with the avo shockies but double check the spring rates and length for your application.
I agree on the diff issues. Mines a 6 speed T56 box and gearing is too low. 6th is great for the freeway but I'd go a 5 speed if doing it again, I'm too busy on trackdays grappling with 4th and 5th on the straights. I'm looking for a taller diff.
Also be wary when ordering your wheels as the offset will differ depending on which Nissan rear end you source. They're generically R32 and 33's but widths (and ratio) vary depending on series, so if your offsets and rim sizes are out you'll get guard clearance problems. So get the whole thing fitted up before you buy wheels I suggest and measure where your hubs are for correct offset. Caster/camber adjustments are greatly improved with aftermarket suspension mods as well.
These issues are covered at length on this forum.
I'm trying to recall other issues during my build, but funnily you forget the frustrations 'cause the whole process for me was so satisfying and fun.
Ford or GMH? ........... who gives a toss, I'm really happy with my Windsor. Any V8 in a 1000kg car is more power than most can effectively use
Anyway look forward to your progress.......wish it was me again
