Chassis headers vs Fenderwell headers

can you slide an asbestos sleeve over that trans cable?. The sleeve used on a Hemi (66-72 Hemi) is about 18" long. I have used the sleeve over fuel line near exhaust in past builds with satisfactory results.

the one tube in the fenderwell header is my pick for a big tube RB motor with stock suspension. Always hated the full fenderwell header because of fairly unequal tube length, limited tire size and clearance, and street exhaust hook up.

Good luck
