Hi all, my first post here, no doubt of many, thought I'd add on to a post rather than starting another.
So I have a 71 1300 and looking for the same advice as the OP.
My 'plan' is to add a disc kit at the front with drop spindles - this kit -
https://tinyurl.com/yykejsu9 I plan to drop the rear 1 or 2 clicks but more than happy to take advice on this.
For wheels I want to go with SSP Empi 8 which are 5.5j X 15 -

Welcome to The Lounge! Sounds like you're building a driver with a Cal Look style, which makes sense. No point in building a strip monster that never gets used.
The dropped spindle kits can add width, so you may need to factor a narrowed beam in to the equation. I think the SSP 8s are a reasonable offset though, so you might get away with it as long as you don't go too wide on the front tyres. I don't think you can beat the look of a 145, but you can find tyre calculators online which compare tyre heights. Put the 145 in as a 145/82r15 and look for something in a 165.
As for the back, lowered 2 splines is far too much. One is too much in my opinion - 4 inner and 4 outer the other way should be enough to drop the back a little but still keep that nose down look. A 205 won't fit under the back with long axles - depending on brand a 185 should be plenty, but the tricky bit is getting the height. A 70 profile is good but hard to get. 65 is too low.
