Johnny's 68 Formula S

If it's the original starter, get it out from underneath ( I think, been a while for me) and replace it with a mini starter. WAAYYY better at 1/4 the weight. Do a search on here. I think you can use a late 90's Dakota starter. Hit the wreckers, the new ones appear to be hit n miss.
OK well besides that for now I got spark I hd a cranking and now I lost crank from starter it just clicks now.
Tapped it made sure all connections are tight and cranked over by Harmonic balance so Turns not freely.
Anyway it has headers 340 how in gods name do you get the starter out? It’s freaking tight.
Took inspection cover off maybe have to losen header?
Need to test starter/ rebuilt it.
Thanks
