Well about time someone started a 70 Swinger project thread
Ran a search here and found only 67-69 darts, demons, dusters etc
I will be following you as I myself has an ongoing 70 Swinger project >340, 4sp, 3.91 plum crazy, white vinyl top #'s match

Only it will be hard to keep driving yours and trying to get it done
One thing leads to another and before you know it you keep taking it apart Good Luck
I owned mine since 1978 now its apart in a garage and boxes
LONG story (sadly no pics when it was on the road)
Only the back glass and headliner left
I now want it done in less than 2 years
I plan on starting a thread on here soon also
Did you find your broadcast sheet??
My build date was 6-23-70 LM23HOR320###
