Really nice work going on here SVR...
Thinking and sleeping on it helps a lot... I find myself just wanting to "Get 'R Done" and then I make mistakes and live with them. So take your time and it will work out well.
Good luck on the build - and Enjoy!
Couple ideas you may have seen on my build
1. your radiator - you can mount the electric fan on the front of the radiator and blow through, works the same. I did 2 fans on the front of mine with the little tye wrap dealios. works great!
2. Home Depot sells the "5/16-18 Flange Bolts" for ALL your front clip parts. They just dont stock very many at a time, so start buying ahead of time to stock up.
3. With jacking up your motor and trans - check your pinion angle to the rear end... dont ask how I know this....
4. Hydroboost - Wilwood sells a remote res kit, also you can get AN fittings that go into your booster and the P/S pump and run AN lines if you like that setup better. I got all the AN to JIC fittings on ebay.
