Thanks for the replies guys!
After looking at a 35R powered 2G last night at In-n-out It looks like the dipstick should move easily enough and I may just pull the A/C fan temporarily and replace it with somthing slimmer. If I still had the stock radiator I think it would fit.
Metal Man (metalmanfab.com) can't fit me in for 2 weeks to make the O2 housing so there's no real rush right now.
